Chain Rule

I need some help with the chain rule....Thank you for helping me:)
Question: G(y)=((x-1)^4)/(((x^2)+2*x))^7

I have no idea where to start.

Do you mean
$$\frac{(x-1)^4}{(x^2 + 2x)^7}$$?

If so, you need to apply the http://en.wikipedia.org/wiki/Quotient_rule" [Broken] first, and then apply the chain rule as necessary.
