The equation below describes a circle. what are the coordinates of the center of the circle? (x - 4)2 + (y + 12)2 = 172

The coordinates of the center of the circle are found in (h, k).  The h coordinate is stuck with the x, and the k coordinate is stuck with the y.  They are in the form (x-h) and (y-k).  So if our first center coordinate is found in (x-4), then the h value is 4.  Our other center coordinate is found in (y+12) which started like this: (y-(-12)).  So the k value is -12.  The center then is (4, -12).
