What is synthetic division?

Back

Synthetic division is a simplified method of dividing a polynomial by a linear divisor of the form (x - c). It is faster and requires less writing than long division.

What is the first step in synthetic division?

Back

The first step is to set up the synthetic division by writing down the coefficients of the polynomial and the zero of the divisor (c) on the left.

How do you find the zero of the divisor in synthetic division?

Back

For a divisor of the form (x + a), the zero is -a. For (x - a), the zero is a.

What is the process of synthetic division after bringing down the leading coefficient?

Back

Multiply the zero of the divisor by the number just brought down, then add this result to the next coefficient.
