Combining differientation rules.. (chain, product, quotient)

I know all 3 of the rules (product, chain, quotient) and I know how to apply them to derive a function when that function ONLY uses 1 of those rules. But questions like this confuse me:

y = [ (2x-1)^2 ] / [ (x-2)^3 ]

Sorry if my brackets look a bit weird i'm trying to make the question clear.

So when I look at that it looks like a quotient rule question AND a chain rule question since the function is to an exponent. How do I apply the rules when I have to use more than one of the rule?
