5Remainder Theorem
6Synthetic Division A process for division of a
polynomial by a binomial.
Example 2 Divide
7Step 1 Write the terms of the polynomial in
descending order.
Then write just the coefficients as shown.
8Step 2 Write the constant k, of the divisor x
k to the left
Bring the first coefficient down. Multiply the
first coefficient by k and write the product
under the second coefficient. Add the second
column. Write the sum as shown.

11Factor Theorem
12Example 4
x 2
Subtract 2 from both sides
x 2 0
So, x 2 is a factor
