From here I'm just working with the left side:
(1) a(x^2 + b/a*x + c/a)
Now, we're looking for a perfect square. (x-h)^2 = x^2 - 2hx + h^2
so you match up the similar termsand get:
-2hx = b/a*x
h=-b/2a
plug this into (1) to get the squared term:
a(x^2 - 2hx + h^2 - h^2 + c/a)

now where do these come from, and what is this perfect square think you speak of?
