How To Use the Quadratic Formula by Hector the Battle Droid

By Murray Bourne, 20 Jun 2008

This week's math movie is fun.

The title says it all...

It's quite a clever compilation of social commentary with an important mathematical concept. The quadratic formula arises a lot when solving math problems, because the curve of a quadratic (a parabola) is an elegant simple shape, and can be used to model many real-life situations.

Well anyway, the video is not a bad way to revise the quadratic formula.

HTML: You can use simple tags like <b>, <a href="...">, etc.

To enter math, you can can either:

  1. Use simple calculator-like input in the following format (surround your math in backticks, or qq on tablet or phone):
    `a^2 = sqrt(b^2 + c^2)`
    (See more on ASCIIMath syntax); or
  2. Use simple LaTeX in the following format. Surround your math with \( and \).
    \( \int g dx = \sqrt{\frac{a}{b}} \)
    (This is standard simple LaTeX.)

NOTE: You can mix both types of math entry in your comment.
