... coefficients in k, then Φ(β) is also a root. So any polynomial with coefficients in k of which α is a zero must have factors x − Φi (α) as well, for 1 ≤ i < d. By unique factorization, this is the unique such polynomial. P must be irreducible in k[x], because if it factored in k[x] as P = P1 P2 then ...

... be the product of two irreducible quadratics. Having no zeros does not prove irreducibility unless the degree is 2 or 3. Example 2: Does the real polynomial x4 + 2x2 + 1 have any (real) zeros? Is it irreducible? Solution: Writing it as (x2 + 1)2 we can immediately see that although it has no zeros i ...
