Divide Using Synthetic Division Use synthetic division to find the result when x^4+6x^3-21x^2-15x-9 is divided by x-3

Use synthetic division to find the result when is divided by

Step 1
Write the problem as a mathematical expression.
Use synthetic division to find the result when

Step 2
Place the numbers representing the divisor and the dividend into a division-like configuration.
\xa0\xa0

Step 3
The first number in the dividend is put into the first position of the result area (below the horizontal line).
\xa0\xa0

Step 4
Multiply the newest entry in the result by the divisor and place the result of under the next term in the dividend .
\xa0\xa0

Step 5
Add the product of the multiplication and the number from the dividend and put the result in the next position on the result line.
\xa0\xa0

Step 6
Multiply the newest entry in the result by the divisor and place the result of under the next term in the dividend .
\xa0\xa0

Step 7
Add the product of the multiplication and the number from the dividend and put the result in the next position on the result line.
\xa0\xa0

Step 8
Multiply the newest entry in the result by the divisor and place the result of under the next term in the dividend .
\xa0\xa0

Step 9
Add the product of the multiplication and the number from the dividend and put the result in the next position on the result line.
\xa0\xa0

Step 10
Multiply the newest entry in the result by the divisor and place the result of under the next term in the dividend .
\xa0

Step 11
Add the product of the multiplication and the number from the dividend and put the result in the next position on the result line.
\xa0

Step 12
All numbers except the last become the coefficients of the quotient polynomial. The last value in the result line is the remainder.

Step 13
Simplify the quotient polynomial.
