# How do you simplify (x + 8)^2?

Sep 18, 2016

${x}^{2} + 16 x + 64$

#### Explanation:

This is due to the fact that if you separate it, you will get $\left(x + 8\right) \left(x + 8\right)$. I'm going to assume your teacher taught you how to FOIL.

So you FOIL it out, and you get

${x}^{2} + 8 x + 8 x + 64$

Then you combine like terms giving you

${x}^{2} + 16 x + 64$
