Week 14 PreCalc 11

This week in PreCalc 11 we learned about multiplying and dividing rational expressions. First step in any equation is to simplify it if possible, ex:


After you can then figure out what x and sometimes y can’t be by looking at the denominator and if x can make the denominator 0, then those numbers can’t be x, ex:


After you state what x and y can’t be you then eliminate everything you can and then you have an answer.

Then for dividing you just have to state the restrictions for both the numerator and the denominator of the fraction after the divide signal and also under the one on the left of the divide signal. Then multiply the reciprocal of it.
