Searching roots for three degree polynomials with the help of Mathematica

Mathematica is a mathematical computer program that represents an
exceptional tool to create and teach mathematics.  At present, the
visualization and model of maths with mathematical assistants such us
Mathematica, play a very important role in the teaching of mathematics.  In
this paper features of Mathematica have been used to find polynomial roots.  A
new method has been developed  to find exact polynomial roots, without using
complicated techniques, with the help of the program. This method is presented
for three degree polynomials. It is supported in reducing a general polynomial
to one in the form x^3-b, whose roots are easily calculated.
