Best ResponseYou've already chosen the best response.1you can do this by converting your equation to the form (x  a)^2 + (y  b)^2 = r^2 where the center is (a,b) and radius = r you do this by a process called completing the square

Best ResponseYou've already chosen the best response.1and y^2 + 12y = (y + 6)^2  36

Best ResponseYou've already chosen the best response.1so we get (x 4)^2 + (y + 6)^2 = 8+16+36 = 60
