Well, it only works for your particular example. Doing the same thing
for log(x^3-78*x+90)+1000*x presents difficulties too.

Yes, this would be a better challenge. What are the three roots of your
expression? You probably have to use big floats to find them and to
distinguish them from the infinities. A less difficult challenge is to find
the infinities.
