Let c = 9 and d = 14
(a) Find a polynomial with constant term c that is reducible over Q. Verify that Eisenstein’s
Irreducibility Criterion does not apply to your polynomial.
(b) Find a polynomial with constant term d that is irreducible over Q but for which Eisen- stein’s Irreducibility Criterion does not apply.
Sorry, I thought the link would be more clear!
