Code:


\<< \-> A B C \<< A B C \->V3 PROOT \>> \>>

I tried the method of Joe Horn, and... it works. Even if the solutions are complex.

The three coefficients have to be integer or real numbers, then everything is fine.

As you say, that won't accept complex coefficients.

Another simple program that takes coefficients from the stack:

Code:


« →V3 'X' PEVAL 'X' QUAD
»

This won't accept complex coefficients either. Also, it won't find complex solutions.
