This could be done directly, _if_ the file was done using LaTeX and _if_ the creator of it put in <alt> text for the equations which is either the LaTeX source for the equation or a nicely written out textual version of the equation.
But most people who care enough to do that also make the source available.
The bottom line is .pdf is an end-format, not an intermediary format and it's always better to go back to the source.
