Topics Covered

Quadratic Equations

Quadratic equations and functions involve variables squared. Students learn to solve quadratics by factoring, completing the square, and using the quadratic formula, and to analyze quadratic functions through their graphs (parabolas).

Quadratics model many real-world phenomena including projectile motion, area optimization, and profit/cost relationships. They're fundamental to algebra and calculus.

Teaching Tips

Teach all solving methods and when to use each. Connect factored form to x-intercepts graphically. Use graphing technology to explore parabola transformations. Model completing the square step-by-step. Practice with real applications like projectile motion.

Quick assessment ideas

Test quadratic solving using multiple methods. Include graphing parabolas and identifying key features. Ask students to solve application problems (projectile motion, area). Test discriminant understanding for predicting solution types.
