The vertex for a parabola in the form f%28x%29=ax%5E2%2Bbx%2Bc has an x-coordinate equal to %28-b%29%2F2a and a y-coordinate of f%28%28-b%29%2F2a%29.

For your problem:
a=1
b=1
c=-12

So calculate %28-b%29%2F2a, then substitute this value for x in your equation and do the arithmetic. Your two calculations will provide you with the x and y coordinates of your vertex.
