Question

In part (ii) can the polynomial x^3 + x + 1 be factored in Z3(x)? and if so, what are the factors? (x - 1)^2 as f(1) = 0 mod 3? B. If R = Z[x] is the polynomial ring over Z, decide whether the following ideals are maximal ideals of R and justify your reasoning: (i) I = (3, x^2 + 1); (ii) I = (3, x^3 + x + 1).
