inline
^^^^^^
As with other markup, there is a directive and a mode:

to insert :math:`c= \pm \sqrt{a^2+b^2}` in your code, just prepend it with the
:math: mode tag::

The quadratic formula gives in general, two solutions to the equation
:math:`ax^2 + bx+c=0`: 

.. math::  x = \frac{-b\pm \sqrt{b^2-4ac}}{2a}
   :label:  quadratic

in your code, just prepend it with the ``..math::`` directive::

   .. math::  x = \frac{-b\pm \sqrt{b^2-4ac}}{2a}
      :label:  quadratic

The ``:label:`` option creates a label and allows us to refer to the
equation elsewhere (see :eq:`quadratic`).
