Professor, I did a quick vid on the quadratic that I have been teaching my "kids" since last year. It came from Professor Po-Shen Loh; and then I simplified it rather radically. If you'd like to share it, you're welcome to. It's for the world. Or do your "own" spin on it. Thanks!

1:32 If the discriminate, b^2-4ac, is a perfect square, you know the quadratic is factorable. It is.
