Homework Help: pre-calculus

Posted by muffy on Friday, September 18, 2009 at 9:49pm.

Determine the center and the radius of the following circle:

x^2+y^2+8x-2y=8

so I figured I'd use completing the square after putting it in standard form:

(x^2+8x)+(y^2-2y)=8

I'm not sure where to go from here.
