Quartics

Quartics
is an option for functions that involve solving algebraic equations, that specifies whether explicit forms for solutions to quartic equations should be given.
  • With Quartics->True, roots of quartics are given explicitly in terms of radicals. With Quartics->False, roots of quartics that do not have very simple forms are given implicitly in terms of Root objects.
