:content: "Let <var>a</var><sub><var>n</var></sub> be the largest real root of a polynomial
  <var>g</var>(x) = x<sup>3</sup> - 2<sup><var>n</var></sup>·x<sup>2</sup> + <var>n</var>.
  \ \nFor example, <var>a</var><sub>2</sub> = 3.86619826...\n\nFind the last eight
  digits of ![p356_cubicpoly1.gif]({{ images_dir }}/p356_cubicpoly1.gif).\n\n<u><i>Note</i></u>:
  ![p356_cubicpoly2.gif]({{ images_dir }}/p356_cubicpoly2.gif) represents the floor
  function.\n\n"
