Quadratic Equations Reveal A Wealth of Information

An excerpt from our conversation in class today...

Conclusions We Can Draw Based on the Matching Activity we Explored on page 29 of Frogs, Fleas and Painted Cubes

1. All quadratic equations can be written in either factored or expanded form
2. The expanded form will always contain a variable being squared while the factored form will always involve the product of two variables
3. It is the factored form that reveals a great deal about the graph of the parabola
