**Warning:** the following might be (is likely to be) an incomplete solution.

Graphing the

That is

(see below)

suggests **might** be a zero for the given expression.

That is **might** be a factor of

Using synthetic division confirms this possibility and gives

as a factorization.

So far I have not been able to factor this second term. Perhaps someone else may do better.
