Firstly set it
This leaves us with:
Then we can use the factor theorem to find one of our roots.
Start with

Very sorry I think I've done something wrong but I thought I'd send you my working a)because I find sometimes reading what someone else has done, even if wrong, helps to solve things and b)because I cant bring myself to get rid of that working.
It could be possible that you just need a factor higher than I'm using so feel free to try some, and if so you'll need to do some algebraic long division. Happy to show you this if you find a factor!
