## Homework Statement

I've got a fraction here:

[itex]\frac{14+14\sqrt{3}}{-8}[/itex]

Why is it you can take a 2 out of the bottom and top to make it the following?

[itex]\frac{7+7\sqrt{3}}{-4}[/itex]

I'm lost in figuring out how this works. I thought the top was like having (14+14x), where you can take a 14 out of each term and make it 14(1+x).
