Quadratic Equations

ax^2 + bx + c = 0, where a, b, and c are constants

Where a and b are real numbers, and c can be complex, this equation is the most basic form of the quadratic equation.

The Quadratic Formula

x = (-b ± √(b^2 - 4ac)) / 2a

Examples:

Example 1: 0 = 2x^2 + 4x + 1

x = (-4 + √(-4 - 4)) / 2(2)

Example 2: 0 = 2x^2 - 5x + 2

x = (-(-5) ± √((-5)^2 - 4(2)(2))) / 2(2)
