The simplify calculator rewrites an algebraic expression in its simplest form. It expands brackets, combines like terms and cancels common factors, then shows both the factored and expanded versions so you can choose the one your teacher expects.
How to use the simplify calculator
- Enter an expression such as
(x+1)^2 - (x-1)^2. - Press Enter.
- Compare the simplified, factored and expanded forms.
What “simplified” means
- No brackets left that can be multiplied out (unless factored form is wanted).
- Like terms combined: 2x + 3x = 5x.
- Common factors cancelled in fractions: (x² − 9)/(x − 3) = x + 3.
Example: (x + 1)² − (x − 1)²
- Expand: x² + 2x + 1 − (x² − 2x + 1).
- Distribute the minus: x² + 2x + 1 − x² + 2x − 1.
- Combine like terms: 4x.
Questions about simplifying
What are like terms?
Terms with exactly the same variables raised to the same powers, such as 3x² and −5x². Only like terms can be added together.
Does simplify solve the expression?
No. An expression has no equals sign, so there is nothing to solve. To find x, use the equation solver.
Can it simplify fractions with variables?
Yes, rational expressions such as (x² − 9)/(x − 3) are reduced by cancelling common factors.
