.. math::

   (a + b)^2 = a^2 + 2ab + b^2

   (a - b)^2 = a^2 - 2ab + b^2

.. math::
   \cos (2\theta) = \cos^2 \theta - \sin^2 \theta
.. math::

   (a + b)^2  &=  (a + b)(a + b) \\
              &=  a^2 + 2ab + b^2

   \begin{eqnarray}
      y    & = & ax^2 + bx + c \\
      f(x) & = & x^2 + 2xy + y^2
   \end{eqnarray}

.. math::
   :nowrap:

   \begin{eqnarray}
      \sqrt{   (k-0)^2  +( -2k + 2)^2} &=& \sqrt{(k +2)^2 +(-2k +6)^2} \\
      \Rightarrow k^2 + 4k^2 -8k +4 &=& k^2 +4k +4 +4k^2 -24k +36 \\
      \Rightarrow -8k +4 &=& 40 -20k \\
      \Rightarrow 12k &=& 36 \\
      \Rightarrow k &=& 3 \\
   \end{eqnarray}
