Question

What is the center of (x + 2)2 + y2 = 36?

Question 8 options:

(0, -2)

(0, 2)

(-2, 0)

(2, 0)

Answer 1

The general form of the equation of a circumference is:
`(x-a)^2+(y-b)^2=r^2`, where
`(a,b)` are the coordinates of the center and
`r` is the radius. By comparison with the given equation, the center is
`(-2,0)`.

Answer 2

The center is (-2,0)
