Complete the square and write the equation in standard form. Then give the center and radius of the circle.x2 + 8x + 16 + y2 + 2y + 1 = 36
A. (x + 1)2 + (y + 4)2 = 36
(-1, -4), r = 6
B. (x + 4)2 + (y + 1)2 = 36
(4, 1), r = 36
C. (x + 1)2 + (y + 4)2 = 36
(1, 4), r = 36
D. (x + 4)2 + (y + 1)2 = 36
(-4, -1), r = 6
