Just add a bit of whitespace to the right and left:

   \dfrac{\,\dfrac{9+3x-2x^2}{x^2-16}\,}
         {\,\dfrac{4x^3-9x}{2x^2+5x-12}\,}

You may want to add a \vphantom command as well to separate the
fractions from the main bar a bit more.


  \dfrac{\,\dfrac{9+3x-2x^2}{x^2-16}\,}{\,\dfrac{4x^3-9x}{2x^2+5x-12}\,}.
