The essay named Fractions in the Special Topics section of this website should be used as a supplement to his chapter. The essay strongly emphasizes the connection of general rational expressions with familiar ordinary arithmetic fractions.
1. Find the domain of a rational expression.
2. Simplify rational expressions.
3. Multiply rational expressions.
4. Divide rational expressions
1. Know the definition of rational expression.
2. Know the definition of domain of a rational expression.
If you understand the previous material you should be able to answer the following questions.
Each of the individually listed exercises should be done. In each of the lists (like 5 - 12) work as many as needed to insure that you understand the concept being illustrated or utilized. Most of these questions or question types are included in the MyMathLab homework requirement. If a particular concept is difficult for you, you should study the related text material and then try to answer some additional questions from the list provided by the department. In each case you are expected to make an honest adult evaluation of your understanding of the concept. Your ability to answer these questions is one tool to help you make that evaluation.
