The Fraction Decomposition Calculator is an advanced mathematical tool designed to break down complex rational fractions into simpler partial fractions. This process is widely used in algebra, calculus, engineering, and higher-level mathematics to simplify integration and equation solving.

In many mathematical problems, especially in calculus, a complicated fraction can be difficult or even impossible to integrate directly. Fraction decomposition helps rewrite such expressions into simpler components that are easier to work with. This calculator automates the entire process, saving time and reducing human error.

Whether you are a student, teacher, or engineer, this tool helps you understand how a complex fraction can be rewritten in simpler forms step by step.


What is Fraction Decomposition?

Fraction decomposition is a method of breaking a rational expression into simpler fractions whose denominators are factors of the original denominator.

For example:

A complex fraction like:

(2x + 3) / (x² - x - 2)

can be decomposed into:

A / (x - 2) + B / (x + 1)

This transformation makes integration and simplification much easier.


How Fraction Decomposition Calculator Works

The calculator performs the following steps:

Step 1: Input Expression

You enter a rational fraction (numerator and denominator).

Step 2: Factor Denominator

The tool factors the denominator into linear or irreducible quadratic factors.

Step 3: Setup Partial Fractions

It assigns unknown constants (A, B, C...) based on factor types.

Step 4: Solve Coefficients

The calculator solves equations to find values of constants.

Step 5: Final Output

It displays the fully decomposed partial fraction form.


Required Inputs

To use this tool effectively, you need:

  • A valid algebraic fraction (numerator and denominator)
  • Polynomial expressions

Step 3: Solve coefficients
A = 3, B = 2

Final Answer:
3/(x - 4) + 2/(x + 1)
