3.8.1 Partial Fractions
The next is a flowchart for partial fraction expansions.
The partial fraction expansion for,
Consider the example below where the order of the numerator is larger than the denominator.
When the order of the denominator terms is greater than 1 it requires an expanded partial fraction form, as shown below.
We can solve the previous problem using the algebra technique.
