general equation: Ax^2+Ay^2+Cx+Dy+E=0 , A not= 0
Show that the center of the circle is the point
(h,k)= (-C/2A , -D/2A)
I don't mind even if you dont answer, but can you give some hints? maybe some solutions?

show also that the squre of the radius is
r^2= C^2+D^2-4AE / 4A^2
Apply then determine the center and radius of a circle with: 3x^2 + 3y^2 - 12x + 6y - 60=0
Verify you answer
(you dont have to tell my the answers, hints are okay)
