Which completes the work correctly?
Mrs. Culland is finding the center of a circle whose
equation is x2 + y2 + 6x + 4y - 3 = 0 by completing the
square. Her work is shown.
x2 + y2 + 6x + 4y - 3 = 0
(x - 3)2 + (y-2) = 42, so the center is (3,2).
O (x + 3)2 + (y + 2)2 = 42, so the center is (3, 2).
O (X - 3)2 + (y - 2)= 42so the center is (-3,-2).
O (x + 3)2 + (y + 2)2 = 42. so the center is (-3,-2).
x2 + 6x + y + 4y - 3 = 0
(x2 + 6x) + (y2 + 4y) = 3
(x2 + 6x + 9) + (y2 + 4y + 4) = 3 + 9 + 4
