Question 319653: I need to solve: Find the center and radius of the graph of the circle. The equation of the circle is written in general form. Then graph the circle.
x^2 + y^2 + 10x - 16y - 32 = 0

rearranging and completing the square(s) ___ x^2 + 10x + 25 + y^2 - 16y + 64 = 32 + 25 + 64

(x + 5)^2 + (y - 8)^2 = 11^2

center is (-5,8) and the radius is 11
