Question 666466: This section is about the square root property and completing the square.
x^2-6x+9=36
I actually don't really know what to do. I tried completing the square and that gave me (x-3)(x-3)=36, then I got stuck.
I also tried subtracting 36 to make the original equation equal zero, and that left me with x^2-6x-27=0, and I got stuck again. What should I do?

===========
x^2-6x+9 is a square, = (x-3)^2
---
%28x-3%29%5E2+=+36
x-3 = 6 --> x = 9
--------
x-3 = -6 --> x = -3
