**Simple Math-- Need help =/**

**1. Homework Statement [/b**

I am confused on how this equation:

2h + (16/h-8 +2) (-8/(h-8)^2

is simplified to this equation:

2h - 128 (h-8)^3 - 16/(h-8)^2

Simplifying skills.

Well, I know that they got the number 128 from multiplying 16 and -8 together and how they got -16 by multiplying 2 and -8 together. Now, what I don't get is getting (h-8)^3 from (h-8)... SOMEONE PLEASE HELP?
