5.27.13 Factoring xn in a polynomial: factor_xn
The factor_xn command factors the largest power of the
variable out of a polynomial, writing it as the product of a monomial
of largest degree and a rational function having a non-zero
finite limit at infinity.
-
factor_xn takes one argument:
P, a polynomial.
- factor_xn(P) returns P
written as the product of its monomial of largest degree
with a rational function having a non-zero finite limit at infinity.
Example
Input:
factor_xn(-x^4+3)
Output:
