Finding factors that add to a specific number is part of this process. Some people can do this pretty easily, but others need a more clear process, especially when negative numbers are involved. Try the problems below. If you get stuck, there is a video after #11.

If that part was difficult, the video below describes an organizational tool and process to help figure out those numbers.
Use the skill you just learned and the patterns you recognized from A5-2 to factor the quadratics below. Some people find they need to do the work on paper and some don't. When there are negatives, I often find that scratch paper is helpful.
