Rational Root Theorem
Rational Zero Theorem

A theorem that provides a complete list of possible rational roots of the polynomial equation anxn + an1xn1 + ··· + a2x2 + a1x + a0 = 0 where all coefficients are integers.

This list consists of all possible numbers of the form c/d, where c and d are integers. c must divide evenly into the constant term a0. d must divide evenly into the leading coefficient an.
