Roots

rhs, var]
yields a disjunction of equations which represent the roots of a polynomial equation.

MORE INFORMATION

Roots uses Factor and Decompose in trying to find roots.

You can find numerical values of the roots by applying N.

Roots can take the following options:

	Cubics	True	whether to generate explicit solutions for cubics
	EquatedTo	Null	expression to which the variable solved for should be equated
	Modulus	0	integer modulus
	Multiplicity	1	multiplicity in final list of solutions
	Quartics	True	whether to generate explicit solutions for quartics
	Using	True	subsidiary equations to be solved

Roots is generated when Solve and related functions cannot produce explicit solutions. Options are often given in such cases.

Roots gives several identical equations when roots with multiplicity greater than one occur.
