How Do You Find a Missing Term in a Polynomial?

The instructor does a very good job of explaining all the things you need to do to find the integer values of this given trinomial. She demonstrates how to set up a template to be able to check the signs of the terms. Next step, what are the factors? Then what are all the possibilities of those factors? Plug the factors into the templates and FOIL it. Now you have the integer values you were trying to find.
