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.
