  1. Now that we've had a lot of practice dealing with complex numbers, let's go back
  2. to that original problem we were trying to solve or at least a problem of a
  3. similar form. I want you to find the roots of this equation for a parabola Y
  4. equals X squared plus 4. Remember that a root is an X value when Y equals 0. If
  5. you get more than one answer, I'd like you to note that you should separate them
  6. by commas.
