<font face="Garamond" size="+2">


A quadratic equation is an equation in a single variable where at least one of the terms includes the independent variable raised to the second power.  In standard form:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ ax^2 + bx + c = 0] where *[tex \LARGE a \neq 0]


The quadratic formula is the general solution to a quadratic equation in standard form, specifically:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x_{1,2} = \frac{-b \pm sqrt{b^2 - 4ac}}{2a} ]
