attempts to express all Root objects in expr in terms of radicals.

Details and Options

  • ToRadicals can always give expressions in terms of radicals when the highest degree of the polynomial that appears in any Root object is four.
  • There are some cases in which expressions involving radicals can in principle be given, but ToRadicals cannot find them.
  • If Root objects in expr contain parameters, ToRadicals[expr] may yield a result that is not equal to expr for all values of the parameters.
  • ToRadicals automatically threads over lists, as well as equations, inequalities, and logic functions.
