Abstract:
In this paper we present a versatile technique to solve several types of solvable quintic equations. In the technique described here, the given quintic is first converted to a sextic equation by adding a root, and the resulting sextic equation is decomposed into two cubic polynomials as factors in a novel fashion. The resultant cubic equations are then solved to obtain five roots of the given quintic along with the added root. The technique can be applied to solve several types of solvable quintics, where the roots are related by simple algebraic expressions.
