Suppose that f(x) =g(x)h(x) f ( x) = g ( x) … In mathematics, Eisenstein's criterion gives a sufficient condition for a polynomial with integer coefficients to be irreducible over the rational numbers – that is, for it to not be factorizable into the product of non-constant polynomials with rational coefficients. This criterion is not applicable to all polynomials with … See more Suppose we have the following polynomial with integer coefficients. $${\displaystyle Q(x)=a_{n}x^{n}+a_{n-1}x^{n-1}+\cdots +a_{1}x+a_{0}}$$ If there exists a prime number p such that the following three … See more To prove the validity of the criterion, suppose Q satisfies the criterion for the prime number p, but that it is nevertheless reducible in Q[x], from which we wish to obtain a contradiction. From Gauss' lemma it follows that Q is reducible in Z[x] as well, and in fact can be … See more Generalized criterion Given an integral domain D, let $${\displaystyle Q=\sum _{i=0}^{n}a_{i}x^{i}}$$ be an element of D[x], the polynomial ring with coefficients in D.
