Rewrite the equation in standard form. Find the center and radius of the circle.x2 + y2 + 4x - 12y + 34 = 0
A. (x + 2)2 + (y - 6)2 = 6
center (-2, 6), r = 
B. (x + 2)2 + (y - 6)2 = 6
center (2, -6), r = 
C. (x - 2)2 + (y + 6)2 = 6
center (2, -6), r = 
D. (x + 2)2 + (y - 6)2 = 6
center (-2, 6), r = 6
