I have been working on fractional expressions that become quadratics before they are solved.
There are many possibilities of which I have examined most?
They begin differently and end differently; I have organized them into files according to their endings (this would also be according to their difficulty)
opposite roots
one root zero
identical roots
different roots
extraneous solutions
Inside each file there is a Case List that controls the file's output.
Attached to this post is the corresponding PDF; attached to the next will be the tarball.

Ooops - just a little error to the answers.
..._opposite_roots - the last case
..._one_root_zero - the last case
