Polynomial Synthetic Division Synthetic Division for polynomials. Formula: Divide ax³+bx²+cx+d by (x−k) using synthetic division algorithm. — free online calculator.

Formula

Synthetic division of a3x³ + a2x² + a1x + a0 by (x − k): q2 = a3; q1 = a2 + kq2; q0 = a1 + kq1; remainder = a0 + kq0. Quotient = q2x² + q1x + q0. Limited to cubic polynomials divided by a monic linear divisor.
  • Polynomial Division Calculator calculates its result from a3, a2, a1, a0, k. It uses the formula Calculated with the verified ST Calculator runtime.. Change any input to recalculate the result instantly.
  • The main inputs are a3, a2, a1, a0, k. Enter them in the units and format shown in the calculator.

Example: Polynomial Division

Inputs
  • a3: 1
  • a2: -6
  • a1: 11
  • a0: -6
  • k: 1

Using a3 = 1, a2 = -6, a1 = 11, a0 = -6, k = 1, the calculated result is q2: 1 | q1: -5 | q0: 6 | remainder: 0.
