Synthetic Division Method

Quick method to divide polynomials by (x - c)

Example: Divide x³ + 4x² + x + 6 by (x + 3)

-3 | 1 4 1 6
   |    -3 -3 6
   ---
     1 1 -2 0

Result: x² + x - 2 with remainder 0

About Synthetic Division Calculator

The Synthetic Division Calculator divides polynomials by (x - c) using synthetic division, a faster method than long division. If the remainder is zero, then (x - c) is a factor of the polynomial.

When to Use This Calculator

  • Factor Finding: Check if (x - c) is a factor
  • Quick Division: Faster than polynomial long division
  • Root Testing: Test potential roots quickly

Key Points

  • Works only for divisors of form (x - c)
  • If remainder is 0, (x - c) is a factor
  • Much faster than long division
  • Organized in a compact table

Frequently Asked Questions

What if the remainder is zero?

If remainder is 0, then (x - c) is a factor! The polynomial can be factored further.

Can I use synthetic division for other divisors?

Synthetic division only works for divisors of the form (x - c). For other forms, use polynomial long division.
