8.1 Multiplying and Dividing Rational Expressions

Vocabulary Rational Expression – a ratio of 2 polynomial expressions. Just like reducing fractions, to simplify a rational expression, divide the numerator and denominator by a GCF. A rational expression is undefined when the denominator is equal to zero.

A. Simplify B. Under what conditions is the expression undefined?

Simplify For what value(s) of p is undefined?
