Using a Single Root of a Polynomial
Use rootOf to get a symbolic root of a
polynomial. The call rootOf(p,x) returns a root of p(x).
This creates an algebraic number a, which is a root of the polynomial
returned in symbolic form.
To find the algebraic relation that defines a, use
definingPolynomial
You can use a in any further expression, including a nested
rootOf.
Higher powers of the roots are automatically reduced during calculations.
The operation zeroOf is similar to
rootOf, except that it may express the
root using radicals in some cases.
