By watching this comprehensive set of examples, anyone can go all the way from expanding brackets (often called FOIL) to being able to solve any quadratic equation. This video explains all of the details behind Loh's announcement video showing why each step is mathematically correct. It can be used by students to learn this method, as well as by teachers and parents to understand the logical nuances of this technique, as it was not generally taught before. Students would benefit from it being introduced into the standard curriculum as replacement for the guess-and-check component of factoring.
