Polynomial Calculator
Three tools in one: add or subtract polynomials, multiply them, or classify and evaluate one — every answer with the working shown.
Add or subtract polynomials
Type each polynomial with ^ for powers, like 3x^2+2x-5. Subtraction distributes the minus to every term.
Multiply polynomials
Every term of the first polynomial is distributed across every term of the second — each partial product is shown.
Classify and evaluate
Get the degree, the number of terms, the standard form, and the value at any x.
