3. Solving Polynomial Inequalities

4. Factor & Solve!!

5. Solving Polynomial Inequalities
Place the inequality in standard form.
Factor the polynomial completely and solve.
Use the zeros of the polynomial and sketch a graph using end behavior and your zeros. **Look for bounces**
Highlight the portion of the graph that makes the inequality true.
Greater than- Above the x-axis
Less than- Below the x-axis
Write the answer in interval notation.

6. Solving Polynomial Inequalities
Consider the following inequality:
So the solution is [-4, -3]

7. Let’s Try Another Example
The zeros of the polynomial are 0, 3 and -1. Graph them with your end behavior.

8. You Try!!

9. How are you doing???

10. Special Cases with Bounces!
Nowhere
(can’t include 2)
Everywhere except 2
x = 2
(-, 2) U (2, )
No Solution
Everywhere including 2
Only at one place
x = 2
(- , )
[2]

11. Solve.
[1] U [11, )
