Quadratic Formula What?!?!?!?

Yeah, it's that time again. 9th grade algebra with its quadratic formula and stuff. (Yes, "stuff" is the official term that has been assigned to this lesson). I did find this on YouTube which was very helpful this time around. It was so helpful that we only cried about algebra for 2 hours today. ~Smile~

Only 4 more times to teach 9th grade algebra!
