In Rational Zero Theorem, Dr. Eaton begins with the equation and the list of possibilities before moving into the equation with a polynomial constant and leading coefficient. She also explains how to deal with the theorem when the leading coefficient is equal to one. At the end, Dr. Eaton covers finding the rational zeros before finishing with four comprehensive examples.
Understand the Rational Zero Theorem and the special case where the leading coefficient is 1. Use it to list all possible rational roots of a polynomial.
Use synthetic substitution to test each possible rational root in your list.
After you find the first root, try to factor the quotient to find the remaining roots.
