Find any critical points and relative extrema of the function x^3 - 3xy + y^2 I got (0,0) is a saddle point, (3/2, 9/4) is a relative minimum

Hello, ewkimchi! Find any critical points and relative extrema of: .$\displaystyle f(x,y) \:=\:x^3 - 3xy + y^2$ I got: .$\displaystyle (0,0)$ saddle point, .$\displaystyle (\tfrac{3}{2},\,\tfrac{9}{4})$ relative minimum. I agree!
