If you are teaching factoring and you want students to practice factoring expressions of the form x^2 + bx + c or ax^2 + bx + c it does not work to just pick random values, you are highly likely to create prime trinomials. While it is not so hard to write x^2 + bx + c expressions it is more time consuming to create factorable expressions of the form ax^2 + bx + c.
The purpose of this resource is to offer a pre-made list of such expressions so you can spend your time on teaching the techniques, and not run out of problems. Included are 20 pages of factorable binomial and trinomial expressions, 100 expressions per page. Each page is clearly labeled, the following page is an answer key.
