In this video, I show you the solutions to a general quadratic equation which is the quadratic formula. Then, I show you the words to a song you can sing to "Pop goes the weasel" and sing it. It's easier to remember the formula if you memorize the song. Also included is how to complete the square in order to derive the quadratic formula, showing all the steps.
