Solving polynomials with the unknown "b" from ax2+bx+c
In this section, we will learn how to find all the possible answers to the unknown "b" in the polynomials ax2+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: x2−y2, Factoring trinomials
