Solve the equations and inequalities below. Check your solutions, if possible. Homework Help ✎

Note the absolute value. When is an absolute value greater than or equal to

? all real numbers

Factor, and solve for

. Since this is an inequality, these are the boundary points.

The boundary points areand . Plot your boundary points on a number line. Test a point in each region to see which region(s) make the inequality true.

This is a quadratic equation. Set it equal to

. Then factor and use the Zero Product Property or use the Quadratic Formula to solve.

Fractions represent division. Multiply all terms by

to 'undo' the denominators.
