In this lesson, we will be doing trinomial factoring to find all possible answers for the unknowns in the term in the middle of the polynomials. By doing so, we will need to reverse the process of FOIL so that we can convert the trinomials into two binomials.

Basic Concepts:Factor by taking out the greatest common factor, Factor by grouping, Factoring difference of squares: $x^2 - y^2$, Factoring trinomials,

- IntroductionFOIL method:

i) What is the FOIL method?

ii) How to use it? - 1.Find four examples of k:a)${x^2+kx-8}$b)${x^2+kx+6}$
