Find the positive and negative factors of . Then substitute each of these into the polynomial. If any of them (call it ) gives you after simplifying the left hand side, then is a factor. After you've done that, long divide, follow the same process.

I found a factor , but I can not find the facors of other factor .
Hint : plot your polynomial and have a look at it. Then you should understand why you can't find other factors
You've found the only real root of f(x)=0.
