My first post in this forum was this reply: Re: Short quadratic solver (HP-15C)

Palmer's program uses a different approach: A "Cadillac" Quadratic Solver for the hp 33s and HP35s
My article attempts to explain how it works: Solve the real quadratic equation \(c-2bz+az^2=0\) for real or complex roots.
