Differentiate and simplify:

y=(x+1)(2x-3)[tex]^{4}[/tex]

I got:

8(x+1)(2x-3)[tex]^{3}[/tex] + (2x-3)[tex]^{4}[/tex].

But the answers in the answer booklet say:

5(2x+1)(2x-3)[tex]^{3}[/tex]

I put both answers in Wolfram Alpha and found they were both equal. So this is just a matter of simplifying/rearranging.

Could someone please explain to me how to simplify my answer to get the answer in the booklet? This one's annoying me as I just can't seem to do it.
