It is well-known that Cardano (1539) first published his solution to the gen- eral
cubic equation in his book "The great art, or, the rules of algebra" using the concept
of complex numbers, which was unknown at that time. However, history pages
reveal that Scipione del Ferro (1515) had solved the cubic in a mathematical contest,
but didn't publish his method; and it seems Tartaglia (1535) revealed his solution to
Cardano, who got it published in his name [1, 2].
In this paper, we describe a division method for factoring and subsequently solving
the cubic equation, which relies on derivation of formulas in a logical fashion
instead of intuitive or empirical way, the Viesta's substitution proposes [2].
