This command differs among variants of English:
|
- Factor[ <Polynomial> ]
- Factors the polynomial.
- Example:
Factor[x^2 + x - 6]yields (x + 3) (x - 2).
CAS Syntax
- Factor[ <Polynomial> ]
- Factors the polynomial.
- Example:
Factor[x^2 - y^2]yields (x + y) (x - y).
- Factor[ <Expression>, <Variable> ]
- Factors an expression with respect to a given variable.
- Example:
Factor[x^2 - y^2, x]yields (x + y) (x - y), the factorization of x2 - y2 with respect to x,Factor[x^2 - y^2, y]yields (-x - y) (-x + y), the factorization of x2 - y2 with respect to y.
Note: This command factors expressions over the Rational Numbers. To factor over irrational real numbers, see the IFactor Command. To factor over complex numbers, see the CFactor Command and CIFactor Command.
Note: This command needs to load the Computer Algebra System, so can be slow on some computers.
