Ah, I know which question you're talking about - it's the multiple choice question with 3 different integrals, yes?
Just so you know, for that question, you don't need to evaluate the integrals at all. You technically can, but it's not on the syllabus and it'll probably take longer.

Well the next ones are hyperbolae, can you sketch those?
And if you think about it you only need those hyperbolae to answer the rest of the second part.
Hey, I still really can't follow the question feel so stupid. Im guessing that the max for x^2+y^2+4xy is 3? (Probably wrong) since its = (x+y)^2+2xy and (x+y)^2 is dominant term and we know the max for x+y so we just sub it in to get 3? I don't really know how to do the next 2 parts though, would you please guide me in the right direction?

You're overcomplicating things. When is x^2+y^2 largest, when is xy largest, is there somewhere where both these things happen?
