Write the equation of the circle in standard form. Find the center and radius. Then sketch the graph.x2 + y2 + 6x - 4y - 12 = 0
A. (x - 3)2 + (y - 2)2 = 25
(h, k) = (3, 2), r = 5
B. (x + 3)2 + (y + 2)2 = 25
(h, k) = (-3, -2), r = 5
C. (x - 3)2 + (y + 2)2 = 25
(h, k) = (3, -2), r = 5
D. (x + 3)2 + (y - 2)2 = 25
(h, k) = (-3, 2), r = 5
