How to Solve A Polynomial Inequality - IT FACTORS - SIGN CHART -

How to use a a sign chart to solve a polynomial inequality. EASY First factor and find the roots and then use them to make a sign chart. Use the sign chart to answer the question. Then present your infinite number of x-value answers using interval notation.

Method: Solve using sign charts.

Step 1: Place the inequality in standard form with zero on one side.
Step 2: Find the critical numbers (for polynomials - the x-intercepts.)
Step 3: Create a sign chart by determining the sign in each interval bounded by the critical numbers.
Step 4: Use the sign chart to answer the question.

Solve and graph the solution set.
