Webenough to be universal. One of the most well-known criteria is Eisenstein’s criterion. Theorem 2 (Eisenstein). Let f(x) = a nxn + a n 1xn 1 + + a 1x+ a 0 be a polynomial with integer coe cients such that pja i for 0 i n 1, p- a n and p2 - a 0. Then f(x) is irreducible. Proof. Suppose that f= gh, where gand hare nonconstant integer polynomials.

Webgeneral irreducibility criterion for polynomials is Theorem 1. If K is any field and if G(x) is a key polynomial over a value V of the polynomial ring K[x\, then G(x) is irreducible. Proof. Suppose that G(x) could be factored as G(x) =f(x)h(x). Then this product is equivalence-divisible by G in V. As G is equivalence-irreducible,, WebBut sometimes the use of Eisenstein's Criterion might not be so obvious and a trick may be needed.
