Vieta and Harriot helped to develop a plan for solving cubic equations that involves transforming the original equation into a depressed cubic - one without a quadratic term. They have a second substitution that transforms the cubic into a sixth degree equation which is of quadratic form - having So, given a cubic (real) equation, it is wise to find by trail one root first, for there is certainly one With one root found, the corresponding factor for the other roots will be a quadratic expression. The second step is then solving a quadratic equation. The cubic algebraic equation ax3bx2cxd0 was first solved by Tartaglia but made public by Cardano in his book Ars Magna(1545) after being sworn to secrecyNote that a peculiar property of this solution method is that the root does not become obvious until the last step in the procedure.
