Simplifying Rational Functions with Factoring and GCFs - Problem 7 173 views
If you have a binomial in top of a fraction and monomial in the bottom, many students get confused about which parts can be reduced. Here, we look at a strategy of re-writing the fraction as two separate fractions, and then reducing each one separately. This technique is commonly used in simplifying in the last step of the quadratic formula. Another method is to factor out the GCF, or greatest common factor of both terms in the top, and then reducing that GCF with the denominator.
