represents the sum of for all x that satisfy the polynomial equation .


  • f must be a Function object such as .
  • form need not correspond to a polynomial function.
  • Normal[expr] expands RootSum objects into explicit sums involving Root objects.
  • f and form can contain symbolic parameters.
  • RootSum[f,form] is automatically simplified whenever form is a rational function.
  • RootSum is often generated in computing integrals of rational functions.
