- What are the rules for determining whether a product is positive or negative?
- What are the rules for determining whether a quotient is positive or negative?
- Will the value of x that makes the inequality true be positive or negative?
- If you change the inequality sign to an equal sign, what value of x will make the resulting equation true? How can you use this information to help you find the possible values for x in the inequality?
- How can you keep track of the values you try for x and the results for each value? Can you make a table?
