Multiplying and Dividing Rational Expressions- sounds hard but it’s not if you understand a few things.  First rational expressions are fractions that are made of variable expressions.  Next multiplying and dividing rational expressions follow the same steps as multiplying and dividing numbers.  So as you study this topic in algebra go back and make sure you know how to work with basic fractions.

Key concepts to remember:

* when multiplying fractions multiply across =( numerator x numerator )/ (denominator x denominator)
* when dividing fractions flip the second fraction and multiply
* know how to multiply polynomials
* know the rules of powers and exponents
* always simplify(reduce) your final answer
