Answer:
The center of the circle is (-3,-2)
Explanation:
we know that
The equation of a circle in standard form is equal to

where
(h,k) is the center
r is the radius
In this problem we have

Completing the square
Group terms that contain the same variable, and move the constant to the opposite side of the equation

Complete the square twice. Remember to balance the equation by adding the same constants to each side.


Rewrite as perfect squares

therefore
The center of the circle is (-3,-2)
