# Calculators :: Polynomial calculators :: Expand and Simplify Polynomials

The following calculator can be used to simplify **ANY** polynomial expression.

Example 1: to expand $(x-1)(x+1)$ type **(x - 1)( x + 1)**.

Example 2: to expand $(a + 2b - c)^3$ type **(a + 2b - c)^3**.

Example 3: to simplify
$\left(27(2/3-2x)^3-8(1-9x)\right)/(216x^2)$
type **(27(2/3-2x)^3-8(1-9x))/(216x^2)**.
