This takes a little more work than you think. Theorem 1. The Gauss Lemma and The Eisenstein Criterion Theorem 1 R a UFD implies R[X] a UFD. Proof First, suppose f(X) = a 0 +a 1X +a 2X2 + +a nXn, for a j 2R. Then de ne the content of … 2. Gauss’ Lemma Now we turn our attention to lling the loose end in the proof of Eisenstein’s criterion.

This result is known as Gauss' primitive polynomial lemma. We need to prove a preliminary result first.

Gauss’ Lemma - Tomorrow we’ll prove the famous and enormously useful Quadratic Reciprocity Law, which deals with the Legendre symbol for odd primes. - Our goal today is to understand it for the prime 2. - Namely, what is 2 p ?

We wish to show that this is in fact an equality.

9. Gauss Lemma Obviously it would be nice to have some more general methods of proving that a given polynomial is irreducible.

First, we need the following theorem: Theorem : Let \(p\) be an odd prime and \(q\) be some integer coprime to \(p\).
