We can rewrite %28x-3%29%5E2%2B%28y%2B4%29%5E2=25 into %28x-3%29%5E2%2B%28y-%28-4%29%29%5E2=5%5E2


Recall that the general equation of a circle is %28x-h%29%5E2%2B%28y-k%29%5E2=r%5E2 where (h,k) is the center and 'r' is the radius. So in this case, h=3, k=-4, and r=5 making the center to be (3,-4) and the radius 5 units.
