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.

  • What is a quadratic equation in general form?
  • How do you solve a quadratic equation using the quadratic formula?
  • What is the quadratic formula?
  • How can you remember the quadratic formula?
  • What is the song that sounds like Pop Goes The Weasel to remember the quadratic formula?
  • Why does the quadratic formula work?
  • How does completing the square work?
  • How can you prove / derive the quadratic formula by completing the square?
  • How would you solve 2x^2 - 3x - 7 = 0 using the quadratic formula?
  • What is the discriminant of a quadratic equation?
  • How do you know what the values of a, b, and c are in a quadratic equation?
This video introduces a fun song to sing along with to remember the quadratic formula, and it also derives the quadratic formula by completing the square to solve a quadratic equation in general form. This is a great introduction to the quadratic formula in an advanced Algebra class.
