In this lecture Professor Fraser will teach you Multiplying and Dividing Rational Expressions. You will begin with Simplifying Rational Expressions before moving into Factoring -1. Then, you will start Multiplying and Dividing Rational Expression, Factoring, and ending with Complex Fractions.
To simplify an
algebraic fraction, factor the numerator and denominator completely.
Then cancel common factors. When multiplying or dividing, do the
same thing factor all the numerators and denominators, then
cancel common factors.
If two factors in
the numerator and denominator look almost the same, factor 1 out
of either of the factors and see if you get two identical factors.
