In this section, we will learn how to find all the possible answers to the unknown "b" in the polynomials ${ax^2 + bx+c}$. Similar to the earlier sections in this chapter, we are going to apply trinomial factoring to reverse the process of FOIL to solve the problems.

Basic concepts: Multiplying binomial by binomial, Common factors of polynomials, Solving polynomials with unknown coefficients,

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

- 1.Determine all integers k of the following trinomials.a)${2x^2+kx-5}$b)${3x^2+kx+4}$
