Answer:
Note You need to understand how to multiply algebraic expressions using the distributive law before starting work on this tutorial. If you feel you need to review this, go back to 3. Multiplying and Factoring Algebraic Expression.
Rational Expression
A rational expression is an algebraic expression.
A rational number is any number that can be written in the form a/b, where a and b are integers and b ≠ 0. it is necessary to exclude 0 because the fraction represents a ÷ b, and division by zero is undefined.
The exercises you'll be given won't usually simplify this much, of course.
First, I'll need to flip the second fraction, and convert from division to multiplication. Then I'll factor, and see if anything cancels.
