Divide Using Synthetic Division (x^5+7x^3-8)/(x-1)

$\frac{x^{5} + 7 x^{3} - 8}{x - 1}$

Step 1

Place the numbers representing the divisor and the dividend into a division-like configuration.

$1$	$1$	$0$	$7$	$0$	$0$	$- 8$
	\xa0					\xa0

Step 2

The first number in the dividend $(1)$ is put into the first position of the result area (below the horizontal line).

$1$	$1$	$0$	$7$	$0$	$0$	$- 8$
	\xa0					\xa0
	$1$

Step 3

Multiply the newest entry in the result $(1)$ by the divisor $(1)$ and place the result of $(1)$ under the next term in the dividend $(0)$ .

$1$	$1$	$0$	$7$	$0$	$0$	$- 8$
	\xa0	$1$				\xa0
	$1$

Step 4

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

$1$	$1$	$0$	$7$	$0$	$0$	$- 8$
	\xa0	$1$				\xa0
	$1$	$1$

Step 5

Multiply the newest entry in the result $(1)$ by the divisor $(1)$ and place the result of $(1)$ under the next term in the dividend $(7)$ .

$1$	$1$	$0$	$7$	$0$	$0$	$- 8$
	\xa0	$1$	$1$			\xa0
	$1$	$1$

Step 6

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

$1$	$1$	$0$	$7$	$0$	$0$	$- 8$
	\xa0	$1$	$1$			\xa0
	$1$	$1$	$8$

Step 7

Multiply the newest entry in the result $(8)$ by the divisor $(1)$ and place the result of $(8)$ under the next term in the dividend $(0)$ .

$1$	$1$	$0$	$7$	$0$	$0$	$- 8$
	\xa0	$1$	$1$	$8$		\xa0
	$1$	$1$	$8$

Step 8

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

$1$	$1$	$0$	$7$	$0$	$0$	$- 8$
	\xa0	$1$	$1$	$8$		\xa0
	$1$	$1$	$8$	$8$

Step 9

Multiply the newest entry in the result $(8)$ by the divisor $(1)$ and place the result of $(8)$ under the next term in the dividend $(0)$ .

$1$	$1$	$0$	$7$	$0$	$0$	$- 8$
	\xa0	$1$	$1$	$8$	$8$	\xa0
	$1$	$1$	$8$	$8$

Step 10

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

$1$	$1$	$0$	$7$	$0$	$0$	$- 8$
	\xa0	$1$	$1$	$8$	$8$	\xa0
	$1$	$1$	$8$	$8$	$8$

Step 11

Multiply the newest entry in the result $(8)$ by the divisor $(1)$ and place the result of $(8)$ under the next term in the dividend $(- 8)$ .

$1$	$1$	$0$	$7$	$0$	$0$	$- 8$
	\xa0	$1$	$1$	$8$	$8$	$8$
	$1$	$1$	$8$	$8$	$8$

Step 12

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

$1$	$1$	$0$	$7$	$0$	$0$	$- 8$
	\xa0	$1$	$1$	$8$	$8$	$8$
	$1$	$1$	$8$	$8$	$8$	$0$

Step 13

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

$1 x^{4} + 1 x^{3} + 8 x^{2} + 8 x + 8$

Step 14

Simplify the quotient polynomial.

$x^{4} + x^{3} + 8 x^{2} + 8 x + 8$
