Partial Fraction Decomposition Calculator
Our Partial Fraction Decomposition Calculator helps you to break down a rational expression into simple fractions very quickly and more accurately.
Just enter your rational function and let the calculator perform the partial fraction decomposition for you.
Our partial fraction calculator is very useful for students, tutors/teachers, and anyone working with algebra, calculus, or rational functions. It can make complex algebraic fractions easier to understand and simplify them.
What Is Partial Fraction Decomposition?
Partial fraction decomposition is an algebraic method which is used to rewrite a rational expression as a sum of simpler fractions. A rational expression contains a polynomial in the numerator and second polynomial in the denominator.
For example, a rational function can often be separated into fractions by simple methods of linear factors, quadratic factors, or/and repeated factors.
This technique is commonly used when you are working with algebraic expressions or integration, calculus and other mathematical questions.
How to Use the Partial Fraction Decomposition Calculator
To use this partial fraction decomposition solver is very simple:
-
First of all enter the rational expression into this calculator.
-
But make sure that the numerator and denominator are entered correctly.
-
Now click the calculate/solve button.
-
The calculator will decompose the rational function into simpler partial fractions.
-
Review the result and you can use it to check your manual calculations.
The tool is created to provide a quick way to solve partial fractions online without using complicated calculations.
What Can You Calculate?
Our calculator can help you to calculate:

The results you get depends on the expression you enter and it also can be decomposed into real or complex factors.
Partial Fraction Decomposition Example
Suppose you want to decompose a rational expression such as:
[
\frac{5x+7}{(x+1)(x+2)}
]
The expression can also be written in the form:
[
\frac{A}{x+1}+\frac{B}{x+2}
]
The values of A and B can then be calculated by comparing coefficients or substituting suitable values of (x).
A partial fraction calculator with steps will make this process very easier to follow and can also help to verify the answer got manually.

Partial Fraction Decomposition vs. Simplifying Fractions
Partial fraction decomposition is not simply the same as we compare it with reducing or simplifying a fraction.
When simplifying a fraction, we usally want to cancel common factors and obtain a simpler equivalent expression. With partial fraction decomposition, we want to rewrite one rational expression as a sum of simpler rational expressions.
This diference is particularly important in calculus, where partial fractions are mostly used to make rational functions easier to integrate.
