Use synthetic division to find .
The dividend is , and the root is 2/3.
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, . Bring the first coefficient, 54, down.
Step 3 : Multiply the first coefficient by r : . Write the product under the second coefficient, - 27. Then add the product and the second coefficient, - 27 :
.
Step 4 : Multiply the sum, 9, by r : .
Write the product under the next coefficient, - 27 and add : .
Step 5 : Multiply the sum, , by r :
.
Write the product under the next coefficient, 14 and add : . The remainder is 0.
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 .
