摘要

A nonconstant polynomial B is said to divide a polynomial A if there exists a nonconstant polynomial Q such that \(A(x) = B(x)Q(x)\) . The polynomials B and Q are then called divisors or factors of A.Divisors FactorsFor example, \(3x+2\) and \((4x-1)\) divide \(12x^2 + 5x - 2\) since \(12x^2 + 5x - 2 = (3x+2)(4x-1)\) . We exclude constant polynomials from these definitions to avoid trivialities.
