How to use this calculator

Edit the two polynomials and their variable inside PolynomialGCD.

Tap the math below to edit it and see the result. Once a result is ready, press Tab on a hardware keyboard to accept it. Outside a matrix, Return completes the line; the phone math keyboard has the same Return action.

What to know

Normalization can differ by a nonzero constant; the coefficient field affects factorization.

Mathlean combines visual mathematical input with computation and canvas tools. Results depend on the expression and available engine support; check important answers independently.
