SOLUTION: Please tell me if I am on the right track. I am to sketch the graph and id the foci of: 9(x-1)^2+4(y+3)^2=36. I came up with foci (1,-3+sqrt5) and (1,-3-sqrt5). Which is (1,-.764)

Question 64838: Please tell me if I am on the right track. I am to sketch the graph and id the foci of: 9(x-1)^2+4(y+3)^2=36. I came up with foci (1,-3+sqrt5) and (1,-3-sqrt5). Which is (1,-.764) and (1,-5.236).
Then I am to find the center of x^2+y^2=12x-12y. I came up with the center at (6,-6)with radius sqrt72. How did I do?
