Critical Points

[CatchThis2]

Locate all the critical points of the function F(x,y) 8x-x^2-4xy^2

I know you have to break the problem down into Fx(x,y) Fy(x,y) Fxx(x,y) Fyy(x,y) Fxy(x,y)

Not sure were to go from here

Why don't you start with Fx and Fy and see if you can solve simultaneously Fx = 0 and Fy = 0.
