AP Quadratic Polynomials and Equations Notes Overview

Quadratic equations are one of the most important topics in algebra — they appear in finance, physics, graphs, and countless real-world problem-solving situations. Mastering quadratics builds the foundation for higher-level math and exam success.

Our notes explain each method step by step, with clear examples that make even the trickiest problems easier to understand. Whether you’re preparing for class, revising for a test, or catching up on missed lessons, these notes will help you learn faster and with less stress.

What You’ll Learn

• Definition of quadratic polynomials and the standard form ax² + bx + c
• Factoring methods for both simple and complex quadratics
• Completing the square in easy-to-follow steps
• Applying the quadratic formula in different cases
• Using the discriminant to predict the type of solutions
• Graphing parabolas: vertex, axis of symmetry, intercepts, and shape
• Real-world word problems that use quadratic models

Example from the Notes

Solve: x² – 5x + 6 = 0

Step 1: Factorize → (x – 2)(x – 3) = 0

Step 2: Set each factor equal to 0 → x = 2 or x = 3

👉 Worked examples like this are included throughout, so you don’t just memorize formulas — you understand how to apply them.
