Is this what you mean:
\[\frac{\partial }{\partial x}\left [ \frac{e^{\frac{-(x-a)^2}{4y}}}{2\sqrt{y}}\left ( \frac{(x-a)^2}{2y^2} \right )+1 \right ]?\]

Partial differentiation is basically the same thing as normal differentiation except that it takes all other variables to be constants. Can you factor out the constans in that expression?
