find_root was not as such in my version of Maxima (version 5.9.1,
installed with Debian Sarge) but "interpolate" was and showed exactly the same behaviour.
Using the quote-quote operator did solve the problem.
I also noticed that the word find_root in the texmacs environment causes
the r to be interpreted as a subscript.
The reason why I wanted to solve this equation numerically is because I
think it can't be solved otherwise i.e. as an explicit function of tau_1
and tau_2, or is this a wrong supposition?
