Abstract

In this work we consider polynomials with integer coefficients and study the irreducibility of these polynomials in Q[x]. We will define an equivalence relation over Z[x]\{0} and we will show the polynomials of degree 3 belonging to certain equivalence classes are irreducible in Q[x]. We will also show that, in some cases, the ones of the coefficients of a polynomial determines its class. Finally, we show how we can create irreducible polynomials from a known irreducible polynomial by adding digits to the left of the ones of the coefficients of that polynomial.
