Rational Root Theorem Definitions Steps Examples

Definitions  Rational Root  A root of an expression consisting of a rational number (i.e. no symbols) 2

Steps  Put equation in standard form  Find all the factors of the leading coefficient (q)  Find all the factors of the constant term (p)  Determine EVERY POSSIBLE COMBINATION of p/q  Substitute each “p/q” into the original equation noting the versions that check out. 3
