Synthetic division is a streamlined method for dividing polynomials, especially useful for dividing a polynomial by a linear factor. Unlike traditional polynomial long division, synthetic division uses the coefficients of the polynomial to simplify the process. This method is particularly efficient when dealing with divisors of the form (x + a) or (x – a).
The formula for synthetic division is straightforward:
P(x) / (x – a) = Q(x) + R / (x – a)
Here, P(x) represents the dividend polynomial, Q(x) is the quotient, and R denotes the remainder.

- Review the Results: The calculator provides the quotient and remainder, along with step-by-step workings to verify.
Example of Synthetic Division in Action
Problem
Divide \( 7x^4 + 2x^2 – 2 \) by \( x – 2 \).
Step-by-Step Solution
- Polynomial Coefficients: Write down [7, 0, 2, 0, -2] (filling in missing degrees of x with zeros).
- Set the Divisor to Zero: \( x – 2 = 0 \) gives \( x = 2 \).
- Perform Synthetic Division: Multiply and add iteratively using the divisor’s constant (2).
| Step | Values |
| 7 | 14 |
| 14 | 28 |
Continue multiplying & adding until no coefficients remain.
The quotient would be \( 7x^3 + 14x^2 + 28x \), and the remainder is \(-2\).
Check the Results: The calculator simplifies this process and ensures accuracy.

- Double-Check Coefficients: Ensure all terms, including zero coefficients, are entered.
- Input Polynomials in Descending Order: Start with the highest power.
- Use Correct Signs: For (x – a) input a, while for (x + a), input -a.
