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
o 22 + y2 – 4x - 6y= -16
(x - 2)2 + (y - 3)2 = 5


The equation 2x2 + 2y2 – 8x – 12y + 16 = 0 defines a circle.
