• Roots[lhsrhs, var] yields a disjunction of equations which represent the roots of a polynomial equation.
• 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 |
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.
