##### Command Categories (All commands)

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.

## CAS Syntax

Simplify( <Function> )
Simplifies the terms of the given function, if possible. Undefined variables can be included in the terms.
Examples:
• `Simplify(3 * x + 4 * x + a * x)` yields ` a x + 7x`.
• `Assume(x<2,Simplify(sqrt(x-2sqrt(x-1))))` yields `-sqrt(abs(x - 1)) + 1`
• `Assume(x>2,Simplify(sqrt(x-2sqrt(x-1))))` yields `sqrt(x - 1) + 1`
