Week 15 in Precalc 11

This week we learned how to multiply ugly fractions, which is almost exactly the same as what we were taught around middle school except with a few more extra steps. For this question factoring any numerator or denominator possible will help simplify the question. In the second line we noticed that there were matching terms on the numerator and denominator, and by following the rules of fractions anything over itself is equal to 1, because there’s no point to multiplying by 1 we’re able to just cross out the matching terms leaving us with what ever is left over as our simplified fraction.
