In the 11th century, Omar Khayyam classified all known cubics and gave geometric solutions for them.
Shown here is one of his simpler cases, the solution of a cubic plus sides (linear term) equal to a number.
Amazingly, Khayyam did not have graphing to do this, but constructed his parabolas geometrically.
Luckily we have GeoGebra!
