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 + 6x - 10y + 30 = 0
A. (x - 3)2 + (y - 5)2 = 4
center (3, 5), r = 2
B. (x + 3)2 + (y + 5)2 = 4
center (-3, -5), r = 2
C. (x + 3)2 + (y - 5)2 = 4
center (-3, 5), r = 2
D. (x - 3)2 + (y + 5)2 = 4
center (3, -5), r = 2
