**find a cubic equation with the given roots of 2 & 3+i**

The cubic formula tells us the roots of a cubic polynomial, a polynomial of the form ax3 +bx2 +cx+d. It was the invention (or discovery, depending on your point of view) of the complex numbers in the 16th century that allowed mathematicians to derive the cubic formula, and it was for this reason that people became interested in complex numbers. In this chapter weâ€™ll see what the cubic... 28/11/2011Â Â· given 2 roots â†’ polynomial of degree 2 desired = 5 â†’ multiply obtained polynomial of degree 2 by xÂ³) If any given root is a complex (i.e. of the form a+ib), you MUST also have the root a-ib IF you wish a polynomial with real coefficients.
