Factor Command
From GeoGebra Manual
 |
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.
Hint: In the 
CAS View you can also use the following syntax:
- Factor( <Number> )
- Expresses a number in its prime factorization
- Example:
Factor(360)yields 2³ 3² 5.
- 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 -(y - x) (y + x), 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.
