0 Solving Quadratics by Graphing

I'm still trying to get my Algebra 2 Quadratic Function Unit up in bits and pieces.  I required my students to demonstrate mastery with 5 different methods of solving quadratics.  I presented them in this order:

* Solving by Factoring
* Solving by Square Roots
* Solving by Graphing
* Solving by Completing the Square
* Solving by The Quadratic Formula

One of the first things we did after learning to graph quadratic functions was to discuss what it means to solve an equation.

We completed a Frayer Model for the phrase "Solve A Quadratic Equation."

This year, I am using the TI-Nspire graphing calculators with my Algebra 2 students.  As someone who was trained to use a TI-84 in high school and a TI-89 in college, this has been a big change for me.  But, I've learned to love the Nspire.  I have yet to decide which calculator I will use with my students next year as we transition to Common Core, however.  

I typed up these steps for my students to glue in their notebooks in case they forgot the process to find the solutions graphically.  We did four problems together as practice.
