Solving Quintics by Radicals

Daniel Lazard 1
Abstract : A formula is given for solving by radicals any polynomial of degree 5 which is solvable by radicals. This formula is valid over any field of characteristic different from 2 and 5. The field extension which is generated by the radicals which appear in the result is always minimal, when only one root is produced, as well as when all roots are given. This formula has been implemented in Maple.
