Synthetic Division

Front

What is synthetic division?

Back

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

How do you set up synthetic division?

Back

To set up synthetic division, write the coefficients of the polynomial in a row. If the polynomial is missing any degrees, use 0 as the coefficient for those degrees.

What do you do with the number in the left-hand box during synthetic division?

Back

The number in the left-hand box is the value of 'c' from the divisor (x - c). It is used to perform the synthetic division process.
