This command works in CAS View only.
- 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.
