non-real numbers. This alternative is appropriate
if you want factorization with respect to more
than one variable.
cFactor(
factored with respect to variable
expression1
factors that are linear in
real constants, even if it introduces irrational
constants or subexpressions that are irrational in
other variables.
The factors and their terms are sorted with
the main variable. Similar powers of

factorization is needed with respect to only that
variable and you are willing to accept irrational
expressions in any other variables to increase
factorization with respect to
some incidental factoring with respect to other
variables.

floating-point coefficients where irrational
coefficients cannot be explicitly expressed
concisely in terms of the built-in functions. Even
when there is only one variable, including
might yield more complete factorization.
