 $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$ $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$
  
 +More math equation options:

 +To display math on its own line, use double dollar signs:
 +$$ \frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x) $$
 +or escaped square brackets:
 +
 +\[ \sin A \cos B = \frac{1}{2}\left[ \sin(A-B)+\sin(A+B) \right] \]
 +A wide range of math environments will work as well:
 +
 +\begin{align*}
 +e^x & = 1 + x + \frac{x^2}{2} + \frac{x^3}{6} + \cdots \\
 +    & = \sum_{n\geq 0} \frac{x^n}{n!}
 +\end{align*}
 +
 +Note that the math environments should not be inside the dollar sign delimiters; the environments should stand on their own with just the \begin and \end statements in order to be parsed correctly. See [[https://www.dokuwiki.org/plugin:mathjax|here]] for what "math environments" means.
