__**Find**__ __**Excluded Values Of Rational Expressions**__

Peter Rubenstein & Nick Bonnet

Summary of Topic:
 * A rational expression is an algebraic fraction whose numerator and denominator are polynomials.
 * Any values of a variable that result in a denominator of zero must be excluded from the domain of that variable.
 * This is called the excluded values
 * To determine the excluded values of a ration expression, you must be able to factor the denominator first.
