What Is Synthetic Division of Polynomials?

Synthetic division is a shorthand method for dividing polynomials that simplifies the process significantly but can be used only when dividing by a linear factor. It is an alternative to the long division method, allowing for faster calculations while giving the same result.

How to Do Synthetic Division?

This method requires fewer steps compared to the traditional long division approach. The only drawback is that the divisor should be a linear binomial.

The steps of the method are the following:

1. Set Up the Coefficients:

   • List the coefficients of the polynomial you wish to divide in descending order of their respective powers.
   • If any terms are missing, represent them using a zero coefficient.

2. Write Down the Divisor:

   • Remember that the divisor should be in the form of $$$x-c$$$, where $$$c$$$ is a constant.

3. Begin the Division:

   • Drop down the leading coefficient of the polynomial; this starts your division.
   • Multiply this coefficient by the constant term of the divisor with the opposite sign.
   • Write this product under the next coefficient and add them.
   • Continue multiplying the constant term of the divisor with the opposite sign by the obtained sum and add the result to the next coefficient in the line.

4. Continue Till the End:

   • Keep doing this process, moving left to right, until you've accounted for all the coefficients.

5. Determine the Quotient and Remainder:

   • The numbers you generate in the final row (except the last one) represent the coefficients of the quotient.
   • The very last number in this sequence is the remainder. If the remainder is zero, the divisor is a factor of the polynomial.

For example, suppose you have the polynomial $$$p(x)=x^3-4x^2+5x-2$$$ and want to divide it by $$$x-2$$$.

Using synthetic division, you'll eventually determine that the quotient is $$$x^2-2x+1$$$ and the remainder is $$$0$$$, indicating $$$x-2$$$ is a factor of $$$x^3-4x^2+5x-2$$$.

Practicing synthetic division on various examples will enhance your understanding and speed. Over time, this method becomes intuitive, allowing you to perform division quickly.
