Date: Jan 21, 2013 5:53 PM Author: Charles Hottel Subject: Find Center and Radius of Circle For This Equation The equation is: x^2 +16x +105/16 +4y^2 +3y = 0

I do not see how to get rid of the coefficient on y^2 without introducing a

coefficient on x^2.

I was able to manipulate this toget : (x + 8)^2 + 4(y +3/8)^2 = 58

but I don't see how that helps. I feel I must be missing something or

perhaps the problem should have had a 4x^2 factor? Thanks in advanc efor

any advice on how to solve this.
