##### Command Categories (All commands)

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.
