Consider the quadratic inequality . Homework Help ✎

Solve for the boundary point(s). How many boundary points are there?

Rearrange the inequality so that you can factor it.

How many solutions do you get when you do this?There are

boundary points. and.Place the boundary point(s) on a number line. How many regions do you need to test?

If there are

boundary points, how many regions are there surrounding those two points on a number line? Test each region and determine which one(s) make the inequality true. Identify the solution algebraically and on the number line.

Substitute a point from each one of these regions into the inequalities.

Does that point make the inequality true? If not, then it is not included..

Make sure to draw this on a number line.
