Question about equation of a circle.

So i'm reviewing some basic algebra for a class and seem to have forgotten some things... Prove that the equation x^2+y^2+x=0 represents a circle and find the center and radius. I do fine with circle equations that require completing the square but am not sure what to do here. Thank you so much in advance!

Hence the equation represents a circle with center (-1/2, 0) and radius 1/2.
