FilledSmallSquare ToRadicals[expr] attempts to express all Root objects in expr in terms of radicals.

FilledSmallSquare ToRadicals can always give expressions in terms of radicals when the highest degree of the polynomial that appears in any Root object is four.

FilledSmallSquare There are some cases in which expressions involving radicals can in principle be given, but ToRadicals cannot find them.

FilledSmallSquare 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.

FilledSmallSquare See Section 3.4.3.
