I eliminated h from the limit, but I still get an undefined answer at 0,0. What's my next step?

The fuck are you doing?
$f_x(0,0) = \lim_{h \to 0} \frac{f(h,0) - f(0,0)}{h} = \lim_{h \to 0} \frac{0 - 0}{h} = 0$

why are you leaving y there when computing the x-derivative? the whole point of a partial derivative is that you get to substitute the other variables in at the start.
