Your polynomial has no integer factor, so there is no "easy" way of factorizing it.
If you want to find the values at which P(x)=0, however, you will need to apply calculus theorems (if you have access to a computer for this homework, use brute force methods like the improved Euler method)
Also, yes, this math homework problem should not be on this board.
Good luck
