And can you also tell me how you got the answer.
Thanks for you help!

None.
The roots are -4, -1, 1, 2
The divisors of 8 are -1, 1, -2, 2, -4, 4. Try them to see if any are roots of the equation..
BTW, you forgot = 0. "This problem", as you state it, is senseless: x^4+2x^3-9x^2-2x+8 is just an expression, it doesn't have any roots!
