I've simplified it to...

(z^2 + 1) (27x^3y^6) / 3y (1/x^3) (1/z+1)

What should I be looking at next? Finding a common factor between both numerator and denominator (I can see three, along with each of the variables). I'd assume before I can factor out though, I should be expanding the brackets further - is that possible at this stage, and if so, how do I go about doing the denominator.

As you can see, I'm pretty lost as to what I should be doing next, so any tips would be great! :)
