Honing my editing skills with five examples which cover everything you need to know about partial fractions. Note: if you're watching this in Marco's 31B class during W20, you don't need to worry about long division (example 4) for the final exam.
Example 1: linear factors 6:44
Example 2: quadratic factors 21:34
Example 3: repeated factors 36:26
Example 4: long division 55:12
Example 5: completing the square 1:09:35
