## anonymous 5 years ago 2(x +7)^2 = 64 what is x?

1. anonymous

You need to isolate x. So start by dividing by 2.

2. anonymous

that would be (x + 7) = 32 rite?

3. anonymous

It would be $(x+7)^2=32$

4. anonymous

yeah ok

5. anonymous

so where do i go from there>

6. anonymous

Well you want to get x by itself and it's in a quantity that is squared. So you need to undo the square...

7. anonymous

would that be $x + 7 = 4\sqrt{2}$

8. anonymous

You bet :) Now just get x by itself!
