## Homework Statement

7X

^{2}(X - 2) - (X - 2)

**2. The attempt at a solution**

Ok, this is really simple but for some reason I can't figure out why the answer has to be (7X

^{2}- 1)(X - 2)

The process is that I have to divide both parts by (X - 2). However, if I do that, I only get 7X

^{2}- 1. Where does that (X - 2) come from for the final answer?
