Synthetic Division Calculator

Divide a polynomial by (x − c) using synthetic division — get the quotient, the remainder, the full table, and step-by-step working.

Divide  P(x) ÷ (x − c)  → quotient + remainder
coefficients (high → low) ÷ (x − c )

Enter the polynomial's coefficients from the highest power down to the constant, separated by commas or spaces (use 0 for any missing term). Then enter c to divide by (x − c).
