Mathematics

The mathematics powered by MathJax:

\[\begin{equation} \sum_{n=1}^\infty 1/n^2 = \frac{\pi^2}{6} \label{eq:series} \end{equation}\]

We can reference the equation as \eqref{eq:series}.

When $a \ne 0$, there are two solutions to $ax^2 + bx + c = 0$ and they are

\[x = {-b \pm \sqrt{b^2-4ac} \over 2a}\]
