show [tex]\frac{1}{(n-1)^2} - \frac{1}{n^2} about= \frac{2}{n^3}[/tex]

n >> 1

2. Relevant equations

3. The attempt at a solution

The first thing I tried was to put the expression all into one term.

so I got [tex]\frac{-n^2 + 3n - 1}{n^3 - 2n^2 + n}[/tex]

Unfortunately, I'm not sure where to go next with this... I assume it has to do with n >> 1. But I really don't see how they get 2/n^3 if anything I would think -1/n ...
