That method is simple as long as we do not have repeated roots for the denominators (I suppose that's why chaste-in-heart-mathematicians do not like this method).Suppose you had:
f(n)/[n*(n-a)^2] this has to be "broken up" as
A/n + B/(n-a) + (Cn + D)/(n-a)^2
Now problem gets complicated (for n=a)......
