Complete the square and write the equation in standard form. Then give the center and radius of the circle and graph the equation.x2 + y2 - 4x - 4y - 8 = 0
A. (x - 2)2 + (y + 2)2 = 16
center (2, -2), r = 4
B. (x + 2)2 + (y - 2)2 = 16
center (-2, 2), r = 4
C. (x - 2)2 + (y - 2)2 = 16
center (2, 2), r = 4
D. (x + 2)2 + (y + 2)2 = 16
center (-2, -2), r = 4
