Polynomial Multiplication Calculator

This tool multiplies two single-variable polynomials and shows every partial product before the like terms are collected. Enter each one in ordinary notation, such as 3x^2 - 2x + 5, and you get the expanded product, its degree, its leading coefficient and its constant term. A second action raises one polynomial to a whole-number power by repeated multiplication, listing each power on the way up. Division is deliberately absent, because the long division and synthetic division pages already lay out that tableau.
