\frac{x^{2} + 9}{x + 3}

$\frac{x^{2} + 9}{x + 3}$

Step 1

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

$- 3$ $- 3$	$1$ $1$	$0$ $0$	$9$ $9$

Step 2

The first number in the dividend

(1)

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

Step 3

Multiply the newest entry in the result

(1)

$(1)$ by the divisor

(- 3)

$(- 3)$ and place the result of

(- 3)

$(- 3)$ under the next term in the dividend

(0)

$(0)$ .

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.

Step 5

Multiply the newest entry in the result

(- 3)

$(- 3)$ by the divisor

(- 3)

$(- 3)$ and place the result of

(9)

$(9)$ under the next term in the dividend

(9)

$(9)$ .

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.

Step 7

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

(1) x - 3 + \frac{18}{x + 3}

$(1) x - 3 + \frac{18}{x + 3}$

Step 8

Simplify the quotient polynomial.

x - 3 + \frac{18}{x + 3}

$x - 3 + \frac{18}{x + 3}$
