Lesson 5: Conic Sections --- Putting It All Together Accel Precalc Unit 2: Algebra Topics Lesson 5: Conic Sections --- Putting It All Together EQ: How do you classify a conic section by its equation? How do you solve a system of quadratic equations?

General Equation of Conics: WHY? WHY? WHY?

Ex. 1 There is no y2 term therefore C = 0!

A = 4 and C = -1, therefore…

A = 2 and C = 4, therefore…

A = 2 and C = 2, therefore…
