Use synthetic division to find
.
The dividend is
, and the root is 4.
Step 1 : Write the terms of the dividend so that the degrees of the terms are in descending order. Then write just the coefficients as shown at the right.
\
Step 2 : Write the constant r of the divisor (x - r) to the left. In this case, r = 4. Bring the first coefficient, 2, down.
\
Step 3 : Multiply the first coefficient by r :
. Write the product under the second coefficient, - 6. Then add the product and the second coefficient, - 6 :
.

Step 4 : Multiply the sum, 2, by r :
.
Write the product under the next coefficient, 5 and add :
.

Step 5 : Multiply the sum, 13, by r :
.
Write the product under the next coefficient, 4 and add :
. The remainder is 56.

The numbers along the bottom row are the coefficients of the quotient. Start with the power of x that is one less than the degree of the dividend. Thus, the quotient is
