 If you try searching for videos on completing the square, you will find that what we call the "standard form" is often called the "vertex form" and what we call "general form" is called "standard form".   Sigh.
Converting a quadratic function to vertex form by completing the square video

Tutorial -- completing the square starts at slide #8



By the way, I'm sad but somewhat relieved that I won't have to buy pizza for everyone after weekly test #2....

A Pledge

After all the quizzes and tests have been written, if no one has committed a certain math crime, I will buy a slice of pizza for every remaining student in the class on the last day of class.

Remember that the square of a binomial (2-term expression) is a trinomial -- don't forget the middle term!!!
