### 5 Multiple Choice Questions

1. If I have a rational inequality, should I multiply both sides by the LCD to eliminate fractions?
2. How do I find the list of possible rational zeros for a polynomial?
3. How many zeros should I expect to find for a 4th degree polynomial?
4. What is the first step for an absolute value inequality that is a 'less than' such as |x+12|<5?
5. If I am told that a polynomial has a zero of -13, what is one of the factors that I KNOW it factors into?

### 4 True/False Questions

1. quadratic inequalities and rational inequalitiesWhat are the two types of problems that use test points?

2. I get a zero on one side of the inequality and get there to be ONE fraction on the other. Then I set the numerator=0 and solve that and also the denominator=0 and solve that. These solutions are my critical points.How do I find the critical points for a rational inequality?

3. You make the two two-part inequalities without absolute values and with the word OR in between. For instance, it would be x+12>5 OR x+12<-5What is the first step for an absolute value inequality that is a 'less than' such as |x+12|<5?

4. I make it into an equation and solve it (by factoring, completing the square, or using the quadratic formula)How do I find the critical points for a quadratic inequality?
