BUILT-IN MATHEMATICA SYMBOL
is an option for functions that involve solving algebraic equations, that specifies whether explicit forms for solutions to cubic equations should be given.
- With Cubics->True, roots of cubics are given explicitly in terms of radicals. With Cubics->False, roots of cubics that do not have very simple forms are given implicitly in terms of Root objects.
- Cubics->True may lead to fairly large outputs.
By default, Reduce does not use general formulas for solving cubics in radicals:
With Cubics->True, Reduce solves all cubics in terms of radicals:
Solving this simple cubic in radicals does not require the general formulas:
