Find Center and Radius of Circle For This Equation
Posted:
Jan 21, 2013 5:53 PM


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.
