The equation is .
Use synthetic division to find .
The dividend is , and the root is 1/2.
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 below.
\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, 0. Then add the product and the second coefficient, 0 : 0 + 2 = 2.
Step 4 : Multiply the sum, 2, by r : .
Write the product under the next coefficient, 3 and add : 3 + 1 = 4.
\Step 5 : Multiply the sum, 4, by r : .
Write the product under the next coefficient, 0 and add : 2 + 0 = 2.
\Step 6 : Multiply the sum, 2, by r : .
Write the product under the next coefficient, -1 and add : -1 + 1 = 0. 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 .
