The equation below describes a circle. what are the coordinates of the center of the circle?
(x+5squared)+(y+2squared)=21 squared

Since, the equation involved is a circle let us clearly write the equation first:


From the standard equation of the circle:



So from the equation given above, our x would be -5, and our y is equivalent to -2.
So the center of our circle is located at the point (-5,-2)

21/2 or 5/2
