the equation for a circle, centered at (h,k) with radius r is
so you need to get your equation in this form. completing the square is one way to do this. separating x and y terms you get
which can then be rewritten using complete the square
which is equivalent to
so your center is the point (-8,12) and the radius would be 7.
