Rational Root Theorem
Rational Zero Theorem

A theorem that provides a complete list of possible rationalroots of the polynomialequationa_nxⁿ + a_n–1x^n–1 + ··· + 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 terma₀. d must divide evenly into the leading coefficienta_n.
