  • ToRadicals[ expr ] attempts to express all Root objects in expr in terms of radicals.
  • 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.
  • See the Mathematica book: Section 3.4.3.
  • See also: Solve, NSolve, RootReduce, Roots.
