[tex]e^{10x -x^2 +4y -y^2}[/tex](adsbygoogle = window.adsbygoogle || []).push({});

I don't know where to start. I have a gut feeling this might require the chain rule, but I don't know how to use it on this thing. I tried doing some silly simplification which resulted in a pair of quotients and products of exponentials and tried to derive those using the quotient rule but it didn't work.

In any case, I need to find the first and second partial derivatives. How do I go about finding them?
