Which equation represents a circle with a center at (-3, -5) and a radius of 6 units?
(x - 3)2 + (y – 5)2 = 6
(x - 3)2 + (y – 5)2 = 36
(x + 3)2 + (y + 5)2 = 6
(x + 3)2 + y + 5)2 = 36

the value in side the bracket of completed square term of x is the negative value of the x coordinate of the centre and the same goes with the y term. i.e the correct answer is the fourth.

remember to express (x+3)×(x+3). as(x+3)^2

c. (x + 3)2 + (y + 5)2 = 36
