You'll probably have to install maxima. As a plus for me, w/maxima I have
the same thing on my pi, my desktop and my phone.
Matematicsa's notation feels awkward to me, but it's been a while. Is the
capital S really required for Solve? Not solve?
And for a bit of math (Hey, the pi is nominally an educational system),
writing it as
-b sqrt(b^2-4ac)
--- +/- -------------
2a 2a
You have
-b/2a is the axis of symmetry & sqrt(b^2-4ac)/2a is the distance to the
roots.
