Définition du théorème de la racine rationnelle

Pour une équation plynomiale avec les coefficients entiers : a_nxⁿ+a_n−1xⁿ⁻¹+…+a₀
Si a₀ et a_n sont des entiers, alors s'il existe une solution rationnelle
on peut la trouver en vérifiant tous les nombres produits pour \frac{\pm diviseurs de a_{0}}{diviseurs de a_{n}}

a₀=2,     a_n=3
Les diviseurs de a₀:    1, 2,     Les diviseurs de a_n:    1, 3
Les nombres rationnels suivants sont des racines candidates :     ± 1, 21, 3
