Partial Fraction Expansion 1, Partial Fraction Expansion, Precalculus
This is the first of three videos on partial fraction expansion. Sal goes over an example that first needs to be divided so that it is a proper fraction. He then continues to demonstrate the decomposition of fractions. At home or in...

Partial Fraction Expansion 3, Partial Fraction Expansion, Precalculus
In the last video on partial fraction decomposition, Sal shows how to solve a fraction with a repeated factor in the denominator. He runs through this interesting problem and gives some insight into how to solve these types of problems,...

Partial Fraction Expansion 2, Partial Fraction Expansion, Precalculus
Partial fraction expansion is further explored in this video. The example problem shown here is of a higher-degree polynomial than the one explored in the first Khan Academy video on this subject.
