Standard Form of Circle Equations

Unit 10: Circles
Lesson 4 of 10

Objective: SWBAT use the method of completing the square to determine whether or not an equation defines a circle and to rewrite circle equations in standard form.

Big Idea: How can I tell if this weird-looking equation will make a circle when I graph it? Students discover how to apply previous knowledge about completing the square to a new problem.
