CFactor Command

CFactor[ <Expression> ]

Factorizes a given expression, allowing for complex factors.

Example:

CFactor[x^2 + 4] yields (x + 2 ί) (x - 2 ί), the factorization of x² + 4.

CFactor[ <Expression>, <Variable> ]

Factorizes an expression with respect to a given variable, allowing for complex factors.

Examples:
CFactor[a^2 + x^2, a] yields (a + x ί) (a - x ί), the factorization of a² + x² with respect to a.

CFactor[a^2 + x^2, x] yields (x + a ί) (x - a ί), the factorization of a² + x² with respect to x.

Note:
This command factors expressions over the Complex Rational Numbers. To factor over rational numbers, see the Factor Command.
