The problem of fraction decomposition it's easy to solve by using the cover up method, when there are no repeated linear factors in the denominator .
Nevertheless it could turn into a hard work if these factors are raised to a high power, where the cover up method doesn't work. This technique shows how to calculate these coefficients without solving large systems of equations with a clever rearrangement of the numerator.
