6.5 Solving Inequalities by Factoring

Steps to Solve equal equal zero open closed true To solve an inequality by factoring, treat the inequality like an sign and solve. Make sure to set the equation to first These are the solutions to plot on the number line. Use an dot for or and a dot for or . Then, test a point in each region. If it makes the statement , shade that region. Write your solution as an inequality. equal equal zero open closed true
