Difference between revisions of "Factor Command"

Revision as of 11:43, 5 August 2011

This command differs among variants of English:

Factor[ <Polynomial> ]: Factors the polynomial.; Example:
Factor[x^2 + x - 6] yields f(x) = (x-2)(x+3).

Factor[ <Polynomial> ]: Factors the polynomial.; Example:
Factor[x^2 - y^2] yields (x + y) (x - y).

Factorizes an expression with respect to a given variable.

Example:

Factor[x^2-y^2, x] gives (x + y) (x - y), the factorization of x² - y² with respect to x.

Example:

Factor[x^2-y^2, y] gives (-x - y) (-x + y), the factorization of x² - y² with respect to y.
