Moving Toward Mastery: Completing the Square (Day 2)

Unit 10: Quadratic Functions
Lesson 18 of 21

Objective: SWBAT graph quadratic functions with irrational roots by rewriting equations in vertex form, and to solve quadratic equations by completing the square.

Big Idea: Students will continue to see that graphing quadratic equations and solving them work in tandem: the better we understand one, the more sense the other will make!
