What is Synthetic Division?

Synthetic division is a shortcut method for dividing polynomials. It’s especially useful when dividing a polynomial by a linear factor of the form (x - r). This method is faster and less prone to errors compared to traditional long division.

How Synthetic Division Works

  1. Arrange the polynomial in descending order of exponents.
  2. Write down the coefficients of the polynomial.
  3. Place the constant term of the divisor (r) at the top of the division bar.
  4. Bring down the first coefficient.
  5. Multiply the result by r and add it to the next coefficient.
  6. Repeat step 5 until you reach the end of the coefficients.

Example of Synthetic Division

Let’s divide x³ + 2x² - 5x - 6 by x - 2

  1. Set up the problem:

      1   2   -5   -6  |  2

  2. Bring down the first coefficient:

      1   2   -5   -6  |  2
  1

  3. Multiply and add:

      1   2   -5   -6  |  2
  1   2    4   -2
    4   -1   -8

  4. The result: Quotient: x² + 4x + 3 Remainder: 0

Our calculator performs these steps instantly, giving you more time to understand the concepts rather than getting bogged down in calculations.

When to Use Synthetic Division

Synthetic division is ideal for:

  • Finding polynomial factors
  • Evaluating polynomials at a point
  • Solving higher-degree polynomial equations

It’s particularly useful in calculus, algebra, and other advanced mathematics courses.

Tips for Mastering Synthetic Division

  1. Practice with simple polynomials first.
  2. Always arrange your polynomial in descending order.
  3. Don’t forget to include zero coefficients for missing terms.
  4. Double-check your input to avoid errors.

Frequently Asked Questions

Can synthetic division be used for all polynomials?

Synthetic division is most efficient for dividing by linear factors (x - r). For more complex divisors, other methods may be more appropriate.

What if my polynomial isn't monic (leading coefficient isn't 1)?

You can still use synthetic division, but you'll need to factor out the leading coefficient first.

How does synthetic division help in finding roots?

If a polynomial P(x) has a factor (x - r), then r is a root of P(x). Synthetic division can quickly test potential roots.

Is there a limit to the degree of polynomials I can divide?

Our calculator can handle high-degree polynomials, but always check the input limits for the best results.
