Convert the inequality to an equation.

Factor using the perfect square rule.

Click for detailed explanation...

Rewrite as .

Check that the middle term is two times the product of the numbers being squared in the first term and third term.

Rewrite the polynomial.

Factor using the perfect square trinomial rule , where and .

Set the equal to .

Add to both sides of the equation.

Use each root to create test intervals.

Choose a test value from each interval and plug this value into the original inequality to determine which intervals satisfy the inequality.

Click for detailed explanation...

Test a value on the interval to see if it makes the inequality true.
