For what value does $\frac{\partial F}{\partial x}$ vanish?

Working is in the attached pictures, easy question just want to make sure I haven't stuffed up

Thank you =D

Mod Edit: Fixed LaTeX. Tip: leave a space between delta and whatever comes after it. If you don't, the LaTeX rendering system doesn't recognize deltaF and similar. Also, for partial derivatives, use \ partial F and \ partial x, not \ delta F and \ delta x.
