Rewrite the following equation in the center-radius form of the equation of a circle.
x2 + 16x + y2 + 18y = -120

A.
(x + 8)2 + (y + 10)2 = 25
B.
(x + 10)2 + (y + 8)2 = 25
C.
(x - 9)2 + (y - 8)2 = 25
D.
(x + 8)2 + (y + 9)2 = 25

Answer:

Substitute (x+4)2−16 ( x + 4 ) 2 - 16 for x2+8x x 2 + 8 x in the equation x2+y2+8x−6y=24 x 2 + y 2 + 8 x - 6 y = 24 . (x+4)2−16+y2−6y=24 ( x + 4 ) 2 - 16 + y 2 ...
