Let A be an ideal of the commutative ring R with identity. There is a canonical homomorphism ϕ A from the polynomial ring R[X] onto (R/A)[X], obtained by reducing all coefficients modulo A. If f R[X], then we say that f is reducible (irreducible) modulo A if ϕ A (f) is reducible (irreducible) in (R/A)[X].
