quadratic equations in algebra

In the previous post we have discussed about how to calculate the domain of a function
 and In today's session we are going to discuss about quadratic equations in algebra. By algebra quadratic equations, we mean that equation written in the form of ax² + bx + c = 0, where we have a ≠ 0.
We say that in above equation, if a = 0, then degree of above equation will become 1, so we say that above equation will be converted in the form of linear equation. As the degree of these equations is 2, so it has two zeroes. It indicates that any quadratic equation has two roots which are represented as (alpha) or (beta). Moreover these roots can be real or imaginary.
There are different ways to find the roots of the quadratic equations. One of the common method to find the roots of the quadratic equation is by finding the factors. These factors can be calculated by splitting the middle term or even by finding the value of the 'x', where the equation becomes zero. Thus we say that we find the zeroes of the given quadratic equations. In some cases, we say that the quadratic equation roots can also be calculated by finding the D = b² – 4 * a * c.
 Now we come to the following three conclusions after getting the value of D:
1.    If the value of D = 0, then the roots are real and equal.
2.    If D< 0, then the roots are imaginary.
3.    If D > 0, then the roots are real and unequal.

how to calculate the domain of a function

-->

Function is a tool that is used to verify the relationship among given values. Now we will understand the concept how to find the domain of a function. Before finding the domain of any function and relation first of all we will learn about the domain of a function.

Set of inputs for a function is called as domain of function. Similarly we can say that set of all possible outputs corresponding to inputs is as known range of function. This concept can be understood with help of an example:

For example: Suppose we have some values (16, -51), (-19, 41), (110, -91), (-105, 198), find the domain of the given elements?

Solution: According to the definition of domain of function we can choose the domain values of above function.

Domain of a given function = 16, -91, 110, -105. Range of a function is given as:

Range is all ‘y’ coordinate values,

Range = - 51, 41, -91, 198.

Domain can be found using steps shown below:

Step 1: To calculate value first take a function or a relation which has ‘x’ and ‘y’ values.

Step 2: As we see above domain of function or relation is all input values.

This is how we can find the domain and range value of a given function and relation.

Pre algebra Practice

In the previous post we have discussed about How to get Free Algebra Problem Solver and In today's session we are going to discuss about Pre algebra Practice. In order to learn about the algebra and the operations related to algebra, we need to first learn how the terms are formed and how the expressions of the algebra are written.
 In algebra, we basically need to write the expression , which are transformed from the sentences.  Let us look at the  following statements and learn how these statements are converted in the form of the algebraic expressions.
In case if we  have the statement twice the number added to three times of the number gives 20. So here we observe that the number which we are talking about is not known. So we need to write the  umber as a variable. Let the number be X. Now we need to write the above statement in the form of the expression. So it will be written as follows :
2*x  + 3* x = 20
 Now we observe that the number will be represented by the variable x. So we can find the value of the variable by simply solving the equation.

 Pre Algebra Practice for learning algebra is also available online which makes the beginner learn how to form the expression with the help of the statement and then how to solve the expressions in order to get the result of the equation. We need to learn some set of rules in order to solve the given expressions and get the value of the variables. To learn about the  Potential And Kinetic Energy,  we need to understand the difference between the two types of energy and how one form of the energy is transformed to another form of energy. It will help us to solve the numerical problems too. Icse 2013 Question Papers are also available online, which can be downloaded by the students to get the idea of the pattern of the paper. 

How to get Free Algebra Problem Solver

The problems of Algebra deals with the solving of equations and getting the values of the variables in the equations. The study of Algebra includes the mathematical calculations on the different terms of the expressions. Now we will learn the methods of solving the algebraic expressions.
If we need to add the two algebraic expressions, we must first understand the concept of like terms. Two terms are called like terms if we have the variables of the terms exactly same with the same powers. Addition and subtraction of the two terms is possible only if it has the like terms.
Also we say that the multiplication of the two terms can be done without considering the degree of the algebraic expression.
In order to learn about the algebra in details, we need to  take the help of online algebra tutors. We always have free algebra problem solver, which can help us to learn about the methods of solving the algebraic expressions. Algebraic solver also help us to solve the equations of algebra by using different identities. It also help the learner to learn how the factorization can be done of the different algebraic expressions and how the  results can be used. Proper list of identities is also available online which help the learner to implement the different features of factorization at different types of problems.
We have online tutors which guide the child to understand the concept of splitting, taking common in the given expression and thus to get the roots of the given equation can be calculated. We can also learn about the Potential and Kinetic Energy online and it will be very helpful in solving the numerical problems based on it. , icse books download can be done through internet, which is useful for the learners and guides him time to time. In the next session we will discuss about Pre algebra Practice.

In the previous post we have discussed about pre algebra practice and In today's session we are going to discuss about algebra solver. As we all are very well aware about the concept of algebra that can be consider as a part of math which is combination of operations and their relational rules to solve the real world problem. In the concept of algebra we generally deals with process of finding an unknown value or fill the numerical value instead of any variable that are used in algebraic equations. Basically the concept of algebra popularly used for solving real world problems. In real life some of the problems are defined in the form of algebraic equations which is combination of numerical and alphabetical value.
At school level, the concept of algebra simply defines their solving pattern by describing their formulas, different rules and procedure but this kind of study may be problematic for some students who are not able to understand algebra in once. To overcome from this problem various website provide a guidance on internet. On internet, algebra solver provides a detail guidance and help to understand the concept of algebra.
The basic reason behind using algebra solver is that it helps the students to clearly explain each and every aspect of algebra. Due to algebra solver students make their practices with real world problem in any ways. Due to which they can also handle advance portion of algebra very easily. Due to this technology students can examine their study or preparation time to time by giving online examination which is freely available. Students can also express their views and ask any question without any hesitation. One more advantage of this technology is that they solve the algebraic equation by expressing them step by step and very easy to understand. (know more about algebra solver, here)

pre algebra practice

In the previous post we have discussed about Significant Figures Calculator and In today's session we are going to discuss about pre algebra practice. Algebra is said as the study of statements in the form of the mathematical expressions, where we convert the statements in the form of the constants and variables joined with the help of the mathematical operators. For Pre Algebra Practice, we need to understand how to convert different statements in the form of the expressions.

First thing we must know that the values which are unknown in the expression are represented by some of the variable names. These variable names can be written in the form of the combination of any alphabets and numbers. Suppose we have a statement as follows: 5 added to a number gives 9, then we observe that the number is not known.
Let us assume that number as N.
Thus we can write above statement as :
N + 5 = 9
Now in order to solve the value of the given variable, we must remember that the variable must be placed on the one side of the equation and the constants are taken to another side of the equation. For movement of the constants or the variables from one side of the equation to another, we must take care of the following rules :
· The Positive sign( +) is replaced by a negative sign and the sign of minus ( - ) is replaced to a plus ( + ) sign.
· The operation of multiplication is replaced by the sign of division and the sign of division is replaced by the sign of division, when the term is moved from one side of the equation to another.
This help us to get the value of the variable in the given equation.

Significant Figures Calculator

The significant number can be defined as a consequence to a particular degree of correctness, or rounding the number up and down up to definite number. If we have any number 7.134 then the significant figure is 7. For example: 3.1328 so the significant figures up to three digits are 3.14. Now we will understand about Significant Figures Calculator Significant figure calculator is a online tool which is used to solve any significant figure within a second. Let’s understand some steps to solve the significant figure.

Step 1: First enter a number in first text box.

Step 2: Then put the number to which we have to round the number in second text box.

Step 3: At last enter the solve button to get the result.

For example: Lets we have 9.67 then find the significant figure using calculator.

Solution:

Step 1: First enter the value in first text box. If we enter 9.67 in first text box.

Step 2: Put number of significant figure up to 1 digit in second text box.

Step 3: Then enter solve button. Then we get 9 as a result.

Now we will understand some rules of significant figure rule.

First rule of significant says that the number zero is not counted in any number. We use only non – zero numbers.

Second rule of significant figure says that we can use zero between two non – zero values. We cannot use them in the ending of a number. (know more about Significant Figures Calculator, here)

The third rule of significant figure can be defined as use of 0 in right side of decimal point we have.

For example: Lets we have a decimal number i,e. (1586.00), we can easily see that zero is present to the right side of the decimal point.

Rationalizing the Denominator can be defined as the process in which a fraction is rewrite so that the denominator contains only rational numbers. To prepare for iit exam please focus on iit question paper 2013 and In the next session we will discuss about roman numeral calculator. 

roman numeral calculator

Roman numbers are special kind of number representing system. It is a category of numeric system from the ancient period of ancient Rome. The basic reason behind to call this number as special because it uses a combination of alphabets to represent numerical values. In ancient period of Rome, roman numerals are very popular and common in various field of mathematics. Roman numerals are sometime called as Latin numeric system which does not include any positional value for zero. But today roman numerals are minor used in some of the field like in lists which are denoted by roman numbers, in chords of music, identifying any particular quantity or name and various other fields. The use of roman numerals is not participating in any mathematical concept or field.

Here in this section discussion is based on the topic of roman numeral calculator. This calculator kind of calculator can perform various calculation which are based on roman numerals. Suppose we want to convert any arithmetic number in the form of roman numeral then they can be represented by using roman numeral calculator. Various fundamental operations like addition, multiplication, division and subtraction can be performed by this calculator. To understand the functionality of roman numeral calculator we need to first understand about roman numerals.

In the below we show some of the symbol that shows roman numbers:

1 = I, 2 = II, 3 = III, 4 = IV, 5 = V, 6 = VI, 7 = VII, 8 = VIII, 9 = IX, 10 = X, L = 50, C = 100 and so on. Now we will see how numeral calculator works:

I) First partition the number into above given number. Suppose 16 = 10 + 5 + 1.

If in case there is number 40 then this can represented as 50 – 10 = L – X

II) After that represented them into their corresponding Roman numeral value.

radical calculator

In the previous post we have discussed about multiplication table chart and In today's session we are going to discuss about radical calculator. In mathematics, we will study different types of expression such as polynomial expression. Here we will understand the concept of radical calculator. An expression that contains root values, such as square roots, cube roots are said to be as radicals. For example: √ (u + v), and ³√ (u + v). The value 2 means square root, 3 means cube root and so on. Radicals are represented by the symbol '√'. Now we will see radical calculator.

Radical calculator can be defined as a online tool that is used to add the multiple values within a seconds. Now we will discuss some steps that are used to calculate the radical values.

Step 1: Suppose we have to add two radical values then enter two root values in two text box.

Step 2: Enter solve button to get the result.

Now we will understand it with the help of example:

For example: Suppose we have to add two unlike radicals. 2 √7 + 4 √9 + √7 + 5 √9.

Solution: Here we need to follow some steps so that we can easily add the radical values.

Step 1: Given radical expression is 2 √7 + 4 √9 + √7 + 5 √9, Now we have to add radical values given in the expression.

Step 2: Now we have to find the common term if present in the given radical expression.

In this expression two pairs are same. So we can write them as:

= 2 √7 + 4 √9 + √7 + 5 √9,

= 2 √7 + √7 + 4 √9 + 5 √9,

Now find common term in expression.

= (2 + 1) √7 + (4 + 5) √9, Now we can easily add the radicals.

On adding we get;

= 3 √7 + 9 √9. This is how we can add unlike radicals.

We can also apply the multiplication over the radical expressions.

To Simplifying Square Roots write the radicand as a product of two factors.

In the previous post we have discussed about Math Problem Solver and In today's session we are going to discuss about Simplify Fractions Calculator. We all are very well aware about the number system. Number system can be defined as a collection of various kinds of numbers that are popularly used for solving mathematical problems. A fraction is a type of number system that performs the representation of two whole numbers in the form ratio. Here the word ratio is also a mathematical concept that expresses any two values as one is divisor and another is dividend.

According to standard definition we can say that fraction is way to partitioning any number into n number of equal parts. Suppose 1 / 5, 3 / 4 and so on. Here we can see that there are two whole numbers, the above number refers as numerator and below number refers as denominator. Here we are going to discuss about the simplify fraction calculator. Simplify Fractions calculator is a calculator which is sued for performing simplification of fractional values into their lowest terms.

It means to say that simplify fraction calculator requires to input the whole value into their numerator and denominator field. After that it performs their processing and shows the final result in front of us.

Math Problem Solver

In the previous post we have discussed about Sum and difference formulas and In today's session we are going to discuss about Math Problem Solver. To solving various kinds of mathematical calculative problems by using different mathematical concepts is a very tricky task. In our daily routine life we have to face several problems in which we required to use mathematical concepts. In the same aspect math problem solver can be consider as a tool that helps in describing how to solve mathematical problem. As we define that math problem solver is a tool whose basic task is to integrate problem solving strategies with mathematical skills at one place to solve mathematical problems.

The basic task of math problem solver is that first it analyze the problem then create a mathematical relationship between problem strategies and various concepts of geometry, algebra with arithmetic’s to solve the problem.

Sum and difference formulas

In the previous post we have discussed about percent calculator and In today's session we are going to discuss about Sum and difference formulas. Whenever we deal with trigonometry we deal with the angles of trigonometric function. If we are asked to calculate the value of sin 30 then we can easily say that it is 1 /2 because it is known to us, but if we are asked to calculate the value of sin 15 or of sin 105 then we need sum and difference formulas. If we talk about sum formulas then sum formulas are:

1. sin(x + y) = sin(x)cos(y) + cos(x) sin(y),
2. cos(x + y) = cos(x)cos(y) – sin(x) sin(y), 
3. tan(x + y) = tan(x) + tan(y) / 1 – tan(x) * tan(y).

Here x and y are the two different angles.
Now if we are asked to calculate the value of sin120 , we can calculate it by sum formula as,
we can write sin 120 as sin( 60 + 60) now we will apply sin sum formula as sin60 *cos60 + cos60 *sin60 , the value of sin 60 is 3/2 and value of cos 60 is ½ so the value of sin 120 will be  √3/2 * 1/2 + 1/2 * √3/2 =  √3 /4 +  √3/4 =  √3/2. This is the required solution. (know more about Sum and difference formulas, here)
In the same way we can also calculate the value of other functions , now we will see the difference formulas,
Difference formulas:
sin(x - y) = sin(x) cos(y) - cos(x) sin(y),
cos(x - y) = cos(x) cos(y) + sin(x) sin(y),
tan(x - y) = tan(x) - tan(y) / 1 + tan(x) * tan(y).
Here x and y are the angle of triangles.
Like sum formula we can also apply difference formula  according to our need, if we are asked to calculate the value of sin 15 then we can write sin 15 as sin (45 - 30) and with the help of difference formula we can solve this problem.

percent calculator

Percent is a most useful concept of mathematics that helps in solving various real world problem. The concept of percent are very popular each and every field of life. It performs the various task that set various parameter to accomplish the tasks successfully. The fundamental concept of percent is to perform the comparison of one quantity from other quantity. In simple mean we can say that percent is a way for expressing how a single number is related to another number. (want to Learn more about percent, click here),

According to the mathematical we can say that percent is way to represent a number in the form of fraction that has a denominator value of 100. In real world the concept of percent can be denoted by '%' symbol. If in any case there is number that contain a percent symbol with them it can also be represented in percent form with denominator of 100. Suppose there is a value 45% then it can be represented as 45 / 100. From the above line we can say that the symbol % is equal to the value of 1 / 100.

Here we are going to discuss about percent calculator. It has a very important role in solving various mathematical problem that are exists in real world. Percent calculator perform the various task like converting a number into fraction, transform the fractional value into percent, calculate the mark-sheet's result in the form of percent and so on. Percent calculator has different role in different field but basic fundamental rule is same.

Suppose we want to calculate 25% of $100 then it can be performed very easily.

First we need convert the percent value into fractional form that is

25% = 25 / 100

then perform the multiplication of this value with $100 like below given manner

25 / 100 * $100

=> $ 25
