##### Examples
###### Lessons
1. Find four examples of k:
1. ${x^2+kx-8}$
2. ${x^2+kx+6}$
###### Topic Notes
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.
