This command differs among variants of English:
|
- Factor[ <Polynomial> ]
- Factors the polynomial.
- Example:
Factor[x^2 + x - 6]yields (x - 2) (x + 3).
Note: This command needs to load the Computer Algebra System, so can be slow on some computers.
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.
