The Tartaglia Cardan method is an old mathematical tool (16th century). It has been developed for the resolution of polynomials:

a. x3 + b. x2 + c. x + d = 0

The achievement of its development became possible with the creation of the complex number i (i2 +1 = 0).

It is also a useful tool for the construction of the toy theory called "The theory of the (E) question (TEQ)". This affirmation will be better understood after a lecture of the chapter treating the involution on vector spaces which are equipped with deformed Lie products.
