If the remainder is equal to zero than we can rewrite the polynomial in a factored form as (x x 1) f 1 (x) where f 1 (x) is a polynomial of degree n 1. This process can be continued until all zeros are found. Factoring Division by linear factors of the ...

  By additivity of degrees in products, lack of factors up to half the degree of a polynomial assures that the polynomial is irreducible. Thus, since the quartic x4 + x3 + x2 + x+ 1 has no linear or quadratic factors, it is irreducible.
