Simplify Expression
Enter a polynomial expression in x. The calculator distributes every product, expands integer-power binomials and collects all like terms into a single polynomial in standard form. Useful when an answer needs to come out as a single expression rather than a sum of products.
Frequently asked questions
What inputs are accepted?
Any polynomial expression in x built from +, −, ×, integer-power ^, parentheses and the variable x. Division and trig/log/exp functions are not handled here — use the dedicated tools for those.
Does it factor the result?
No. This tool expands and collects. Use the Factoring Calculator to get the factored form.
What if my expression isn't a polynomial?
The tool reports a clear error. The Symbolic Derivative or Integral calculators handle general expressions in x.
