x^2�16x+63=0
x^2-16x =-63
x^2-16x+64=1 add (16/2)^2 to both sides
(x-8)^2=1 factor
x-8= +-1
x=8+1, x=8-1
x=9, x=7

To complete the square, you want to find the form

By comparing the expanded perfect square equation to your equation, you see that,

I have 63, so I just need to add 1, to have a perfect square form on the left hand side.

Since =1 and =-1, we will solve for two solutions.
First,
