I don't know what \dfrac should be (I assumed \let\dfrac=\frac)
The most easy solutions is probably to put a \ or \, before and after
the content (if I understood your question correctly).
\dfrac{\dfrac{9+3x-2x^2}{x^2-16}}{\ \dfrac{4x^3-9x}{2x^2+5x-12}\ }.
If you use that a lot, something like \def\mainfrac#1#2{\frac{\ #1\
}{\ #2\ }} might be helpful.
