Polynomial long division generalizes numerical long division to algebraic expressions. Divide the highest degree term of the dividend by the highest degree term of the divisor, multiply back, and subtract, then repeat until remainder is lower degree than the divisor. For example, dividing x³+2x²–4x+1 by x–1 systematically yields a quotient x²+3x–1 and remainder 0 if (x=1) is a root. This process underpins factorization, simplifying rational expressions, and advanced calculus tasks. Mastering polynomial long division fosters skillful manipulation of polynomials in proofs and real-world models.
