Fitting data to a curve

I have a table of {x,y} data and a function: a y^2 + b x y + c x + d y + e = x^2 I'd like to do a least fit to determine the constants a, b, c, d, and e. I think the function I want is Fit[] or FindFit[], but I can't coax Mathematica to do this. I'm not entirely sure what to do with that x^2 since it has no coefficient. I've never used these functions before; how can I do this least squares fit? Thanks!
