Core Definitions

A polynomial of degree two is called a quadratic polynomial.

A quadratic polynomial equated to zero is called a quadratic equation.

ax^2 + bx + c = 0

x = (-b ± √(b^2 - 4ac)) / (2a)

D = b^2 - 4ac

Standard Form and Rewriting

a ≠ 0

Solving by Factor Method

If (x - α)(x - β) = 0, then x = α or x = β

Standard Form and Rewriting Equations

A quadratic equation in standard form is ax^2 + bx + c = 0.
