Solving Polynomial Inequalities using the Test Point Method

Find the Polynomial’s zeros

Draw a number line and place all of the Polynomial’s zeros on the graph.

Test all intervals between each polynomial zero on the graph by plugging in one number of choice (located between each polynomial zero) into the original inequality.

If the point agrees with the original inequality, then all numbers between the two polynomial zeros is a solution.

If the point does not agree with the original inequality, then all numbers between the two polynomial zeros is not a solution.

Repeat the process for each interval.

Write your final solution in interval notation.
