How to do Partial Fraction Decomposition?

Partial Fraction Decomposition is an algebraic technique to convert a complex rational function into sum of simple rational fractions.

A rational function is the division of two polynomials. In some cases where the degree of denominator is greater than or equal to numerator, direct integration is quite difficult. To deal with such problems, we adopt a technique called Partial Fraction Decomposition.

The following infographic will help you in understanding how to integrate complex rational function having linear repeated factors.
