My question is soon to follow...

I'm having trouble with the second part of the question. From (i), the first three terms are 32 - 80y + 80y^2. Now how do I find the second part of the question?

OpenStudy (debbieg):

Replace the y in your expression \(32 - 80y + 80y^2\) with \(2x-x^2\). You will get \(x^2\) terms from from both the y term and the \(y^2\) term, so make sure you expand as necessary and account for all the \(x^2\)'s, combine the like terms, and see what your coefficient is.

Okay, got it, thanks! It's fixed now. :D
