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 center is (-2,0)

Answer 2

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 $(-2,0)$.
