Solving polynomials with unknown constant terms

Solving polynomials with unknown constant terms

Similar to the previous section, we will be using trinomial factoring too. Just this time, we are going to look for the constant term in the polynomials instead. The trick is to reverse the process of FOIL so that we can convert the trinomials into two binomials.
Basic Concepts: Prime factorization, Multiplying binomial by binomial
Related Concepts: Factor by taking out the greatest common factor, Factor by grouping, Factoring difference of squares: x2−y2x^2 - y^2, Factoring trinomials
