Elementary Theory of Factoring Trinomials with Integer Coefficients over the Integers
Donnell, William A.
International Journal of Mathematical Education in Science and Technology, v41 n8 p1114-1121 2010
An important component of intermediate and college algebra courses involves teaching students methods to factor a trinomial with integer coefficients over the integers. The aim of this article is to present a theoretical justification of that which is often taught, but really never explained as to why it works. The theory is presented, and a suggestion for an inquiry-based learning project is given.
