Polynomials with integer values.
... many prime values. For instance, the polynomial X n + 105X + 12 is irreducible, by Eisenstein’s criterion (see box). But, it cannot take any prime value because it takes only even values and it does not take either of the values ±2 since both X n + 105X + 10 and X n + 105X + 14 are irreducible, agai ...
