continue the factorization process. and factorize the (x^3-1) it will give you (x-1)(x^2+x+1). therefore the polynomial after factorization becomes

(x^2+2)(x-1)(x^2+x+1).

now how to factorize the x^3-1 ..the (x-1) is a factor of the polynomial x^3 -1 therefore dividing by (x-1) or simply use Horner's method

(Horner's method - Wikipedia, the free encyclopedia ) you will get the result .
