Use the following equation, find the center and raduis:
x^2 + 2x + y^2 + 4y = 20

The center is located at (1,2) and the radius is 25
The center is located at (-1,2) and the radius is 25
The center is located at (-1,-2) and the radius is 5
The center is located at (1,2) and the radius is 5
^That's the one I got, but I just want to double check.
