We worked on review problems on the Moodle.

Your homework for tonight is:
  1. Finish the solving by factoring problems on the Moodle (if necessary).

  2. Organize your notebook (and yourself) for the stretch run.
Here's that video of Arthur Benjamin doing math in his head. He's using (a + b)2 = a2 + 2ab + b2 and (a - b)2 = a2 - 2ab + b2 to help him (but it's still amazing that he can keep track of all the parts in his head).
