I received this article in the Mensa Brainwave newsletter this morning. Having watched many tutoring students struggle with solving Quadratic equations, I am fascinated by the methodology described here. It makes perfect sense, and eliminates the trial and error method used for centuries.
I am without pencil and paper at the moment, but can hardly wait to pull some out and my math books and try the method for myself. In physics, I have run across some whopper Quadratic equations which, even when run through the quadratic formula, are still quite messy. This look like a vastly more elegant approach.
As always, thanks for reading. I can help your student master Quadratic equations by contacting me at firstname.lastname@example.org
