Synthetic Division Calculator: Simplify Polynomial Division

What is Synthetic Division?

Synthetic division is a simplified process of dividing a polynomial by a binomial of the form (x - c). It is faster and more straightforward compared to the traditional long division method. This method is particularly useful for:

Finding the quotient and remainder of a division.
Simplifying polynomial expressions.
Checking whether a given value is a root of a polynomial.

For example, dividing (x^3 + 4x + 8) by (x + 2) becomes a simpler and quicker task using synthetic division.

Frequently Asked Questions (FAQ)

1. What is synthetic division used for?

Synthetic division is a shortcut method for dividing polynomials by a binomial divisor of the form (x - c). It simplifies the process and reduces the chance of errors.

2. Can I use this calculator for all types of polynomials?

Yes, this calculator works for any polynomial that can be divided by a binomial of the form (x - c) or (x + c).

3. What should I enter in the "divisor" field?

Enter the binomial divisor as it appears in your equation. For example, if you are dividing by (x - 5), type (x - 5) in the divisor field.

4. What does the quotient represent?

The quotient represents the result of the division, excluding the remainder. It is expressed as a polynomial.

5. What happens if I make a mistake in my input?

The calculator will provide an error message to guide you in correcting your input.

6. Can this calculator handle negative coefficients?

Yes, the calculator supports negative coefficients and properly processes them in both the dividend and divisor.
