Solve a Quadratic Inequality - SIGN CHART - Let's Do This!

How to solve and graph a quadratic inequality using a sign chart. EASY. Also, graph answers on a number line and use 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 quadratics - 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.
