UPDATE: I have fixed all quadratics, I have added support for negatives and decimals, as well as finishing all forms listed with a 'Y' under 'Solved'. This is version 11, not released to deviantart yet, but version 09 is available for download. Updates will come rather quite frequently (but not on weekends most likely). Here is the code:
Code: Select all
--Solveable# Solved/Negatives/Decimals Type
--0 Y/Y/Y Expression
--1 Y/Y/Y x^2+x+1=0 or x^2+x=1
--2 Y/Y/Y x+1=0 or x=0
--3 Y/Y/Y 1+x=0
--4 N/N/N x^2+1=0
--5 N/N/N x^2=0
