Solving Quadratics by Factoring

Guided Notes
Key concepts students will learn:
- •
The standard form for a quadratic equation is Ax² + Bx + C = 0, where A, B, and C are integers.
- •
To factor a quadratic in the form x² + Bx + C, find two numbers that multiply to C and add to B.
- •
If (x + M)(x + N) = 0, then the solutions are x = -M or x = -N, because anything times zero is zero.
