Concept explainers
One of the common difficulties with studying the material in this chapter is being sure about the task at hand. Are you combining expressions using operations to get another rational expression, or are you solving equations for which the results are numbers that are solutions of an equation? To practice making these decisions, determine for each of the following exercises the type of answer you should get: “Rational expression” or “Solutions.” You need not complete the mathematical operations.
