Complete the square and write the equation in standard form. Then give the center and radius of the circle.x2 + y2 - 2x + 14y + 50 = 81
A. (x + 7)2 + (y - 1)2 = 81
(-7, 1), r = 9
B. (x - 1)2 + (y + 7)2 = 81
(1, -7), r = 9
C. (x - 1)2 + (y + 7)2 = 81
(-1, 7), r = 81
D. (x + 7)2 + (y - 1)2 = 81
(7, -1), r = 81
