What Is a Partial Fraction Calculator?

A Partial Fraction Calculator is an online mathematical tool designed to simplify rational algebraic expressions into separate fractional components.

For example, instead of solving a complicated expression like:

$\frac{5x+7}{(x-2)(x-4)}$(x−2)(x−4)5x+7​

the calculator rewrites it into simpler fractions such as:

$\frac{A}{x-2}+\frac{B}{x-4}$x−2A​+x−4B​

This decomposition makes integration, algebraic manipulation, and equation solving much easier.

The tool automatically calculates the constants and provides the final simplified expression along with the working steps.
