The projects are categorized by their difficulty. If you're not sure about which project to pick, why not take our Quiz to see which project you might be interested in.

Math observations

The first thing we need to do is to get everything on the left-hand side, and 0 on the right-hand side, so we can see if we can factor the quadratic. Then we check each interval with random points to see if the factored form of the quadratic is positive or negative. We put the signs over the interval.

Make sure to use 0 as a test point if you can! The inequality is set up to make a sign chart, since we have 0 on the right-hand side.

This is because squaring an odd number still results in an even number. It might be easier just to use the Completing the Square method above, but we can do it this way, too. The boundaries for the sign chart are these roots, which are approximately — 6.
