% this is the default PlanetMath preamble. as your knowledge % of TeX increases, you will probably want to edit this, but % it should be fine as is for beginners.

% almost certainly you want these \usepackage{amssymb} \usepackage{amsmath} \usepackage{amsfonts}

% used for TeXing text within eps files %\usepackage{psfrag} % need this for including graphics (\includegraphics) %\usepackage{graphicx} % for neatly defining theorems and propositions %\usepackage{amsthm} % making logically defined graphics %\usepackage{xypic}

% there are many more packages, add them here as you need them

The quadratic formula

\begin{equation} x \;=\; \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \end{equation}

can be used to find the solutions (roots) to a quadratic equation $$ax^2 + bc + c \;=\; 0.$$
