11-127.

Solve each inequality algebraically. Then represent your solution on a number line. Homework Help ✎

Factor and use the Zero Product Property to solve for the boundary points. Place the boundary points on a number line then test a point in each region to determine which regions contain the solutions.

Solve two equations to find the boundary points:
