The equation 2x² + 2y2 – 8x - 12y + 16 = 0 defines a circle.
Which of these shows a correct step for determining the center and radius of this circle? Choose all that are correct.
(2x2 – 8x + 16) + (2y2 – 12y + 36) = -16 + 36
(x - 4)2 + (y - 9)2 = 5
(x2 - 4x + 4) + (y2 – 6y + 9) = -8 +13
Ox? + y2 - 4x - 6y = -16
(x - 2)2 + (y - 3)2 = 5
