Solving polynomials with the unknown "b" from ax2+bx+c{ax^2+bx+c}

Solving polynomials with the unknown "b" from ax2+bx+c{ax^2+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{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.
