However, it is sometimes easier to break an integrand up into simpler problems, and for rational expressions we have several forms to recognize. Sometimes the integral of an algebraic fraction can be found by first expressing the algebraic fraction as the sum of its partial fractions. However, you need to learn how to solve simple mathematical problems by hand. The coverup method is a quick way of working out partial fractions, but it is important to realise that this only works when there are linear factors in the denominator, as there are here.

This method is used when the factors in the denominator of the fraction are linear in other words do not have any square or cube terms etc. In this section we will take a look at the process of partial fractions and finding the partial fraction decomposition of a rational expression. The decomposition will consist of partial fractions with linear numerators over each irreducible quadratic factor represented in increasing powers.
