Description

A detailed tutorial on the use of the Quadratic Formula to solve Quadratic Equations. Step by step tutorial including two example quadratic equations for reference. Knowledge of the Quadratic Formula and how to solve Quadratic Equations are a requirement for grade school algebra.

Overview

The quadratic formula follows the form \frac{-b \pm \sqrt {b^2-4ac}}{2a}.

In mathematics, a quadratic equation is a polynomial equation of the second degree. Quadratic equations follow the general form of ax^2+bx+c=0 where x represents a variable, and a, b, and c, represent coefficients and constants, with a≠0 .

The constants a, b, and c, are called respectively, the quadratic coefficient, the linear coefficient and the constant term or free term.
