The polynomial 23 - 2 + 1 has no roots in Zg, so it is irreducible in Zg[] (you don't have to show this). Suppose a is a root of 23 - 2 + 1 in an extension of Zz 1. Show that a +1 and a + 2 are also roots of 23 - 2+1 Conclude that Zz(a) is the splitting field of 23 - 2+1, and thus a Galois extension of Zz. (Hint: Theorem 3 from Chapter 20...
