About Polynomial Multiplication
Polynomial multiplication is a fundamental operation in algebra. It involves multiplying two polynomials, which are expressions consisting of variables and coefficients. To multiply polynomials, you distribute each term of one polynomial across all terms of the other polynomial. Then, you combine like terms (terms with the same power of the variable) to simplify the result.
For example, to multiply (x + 2) and (x - 1), you would do: (x + 2) * (x - 1) = x*(x - 1) + 2*(x - 1) = x^2 - x + 2x - 2 = x^2 + x - 2. This tool simplifies this process by allowing you to input the coefficients and instantly get the coefficients of the product polynomial. It's useful for students, educators, and anyone needing to quickly multiply polynomials without manual calculation.
This calculator uses the convolution method, which is mathematically equivalent to polynomial multiplication. The coefficients you enter should be in descending order of the polynomial's degree. For instance, for x^2 + 2x + 1, enter "1,2,1".
