Adding and Subtracting Rational Expressions - May 21st

Topics for Today:

We will apply our knowledge of adding and subtracting fractions to the concept of adding and subtracting rational functions.  Recall that a rational function is just a "big fraction" - in more technical terms, a rational expression is a fraction containing polynomials in the numerator and denominator.  As with adding numeric fractions, adding rational expressions requires a common denominator, and we apply all the same rules.  To add or subtract fractions with common denominators, you will add or subtract their numerators, and keep the denominator the same.  Once you have performed the required operation, you should always make sure that your remaining fraction (or rational expression) is in simplest terms.
