Answer 11

Oh sorry I was walking to my next class.
What number must be added to both sides of the equation to complete the square?

x^2 - 16x = -8

The first step is to divide -16x in two, it is -8x.
Using this, we can write the first part of the square:
(x-8)(x-8) or (x-8)^2
If we FOIL this out, we get:
x^2-8x-8x+64
=x^2-16x+64
You will have to add 64 to each side:
x^2-16x+64=56
