    How to use Expression Simplifier

    Type an expression to expand it, combine like terms and cancel common factors. The factored form is shown when it differs.

    1. Type an expression such as (x+1)^2 - (x-1)^2 or (x^2-1)/(x-1).
    2. Read the simplified result.
    3. Check the factored form and copy either one.

    Questions

    What does simplifying do?

    It expands products and powers, adds like terms, cancels factors common to a numerator and denominator, simplifies square roots of numbers and rationalises simple denominators.

    Does it handle functions?

    Yes. Terms such as sin(x) or ln(x) are treated as single units, so sin(x) + sin(x) becomes 2sin(x). Exact values such as sin(π/6) = 1/2 are recognised.
