Step 2: Raise both sides of the equation to a power that is the same as the index of the radical. Step 3: Solve the resulting equation; if it still contains a radical, repeat step 1 and step 2. Step 4: Check all potential solutions in the original equation. * To solve a quadratic inequality:

Unformatted text preview: Step 1: Write the inequality as a quadratic equation and solve. Step 2: Use the numbers solved from step 1 to divide a number line into intervals. Step 3: Substitute a test number from each interval into the original inequality to determine the solution set.
