Simplify[ <Function> ]: Simplifies the terms of the given function, if possible.; Example: Simplify[x + x + x] yields the function f(x) = 3x.

Simplify[ <Text> ]: Attempts to tidy up text expressions by removing repeated negatives etc.; Example: For a = b = c = -1 Simplify["f(x) = " + a + "x² + " + b + "x + " + c] yields the text f(x) = -x² - x - 1.

Note:

The FormulaText Command normally produces better results and is simpler.

Note:

This command needs to load the Computer Algebra System, so can be slow on some computers. Try using the Polynomial Command instead.

Simplify[ <Function> ]: Simplifies the terms of the given function, if possible. Undefined variables can be included in the terms.; Example: Simplify[3 * x + 4 * x + a * x] yields xa + 7x.

Note: See also Factor Command.
