$2 x^{4} - 3 x^{3} - 24 x^{2} + 76 x - 60$ by $2 x - 3$

Step 1

Write the problem as a mathematical expression.

$\frac{2 x^{4} - 3 x^{3} - 24 x^{2} + 76 x - 60}{2 x - 3}$

Step 2

Divide each term in the denominator by $2$ to make the coefficient of linear factor variable $1$ .

$\frac{1}{2} \cdot \frac{2 x^{4} - 3 x^{3} - 24 x^{2} + 76 x - 60}{\frac{2 x - 3}{2}}$

Step 3

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

$\frac{3}{2}$	$2$	$- 3$	$- 24$	$76$	$- 60$

Step 4

The first number in the dividend $(2)$ is put into the first position of the result area (below the horizontal line).

$\frac{3}{2}$	$2$	$- 3$	$- 24$	$76$	$- 60$

	$2$

Step 5

Multiply the newest entry in the result $(2)$ by the divisor $(\frac{3}{2})$ and place the result of $(3)$ under the next term in the dividend $(- 3)$ .

$\frac{3}{2}$	$2$	$- 3$	$- 24$	$76$	$- 60$
		$3$
	$2$

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.

$\frac{3}{2}$	$2$	$- 3$	$- 24$	$76$	$- 60$
		$3$
	$2$	$0$

Step 7

Multiply the newest entry in the result $(0)$ by the divisor $(\frac{3}{2})$ and place the result of $(0)$ under the next term in the dividend $(- 24)$ .

$\frac{3}{2}$	$2$	$- 3$	$- 24$	$76$	$- 60$
		$3$	$0$
	$2$	$0$

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.

$\frac{3}{2}$	$2$	$- 3$	$- 24$	$76$	$- 60$
		$3$	$0$
	$2$	$0$	$- 24$

Step 9

Multiply the newest entry in the result $(- 24)$ by the divisor $(\frac{3}{2})$ and place the result of $(- 36)$ under the next term in the dividend $(76)$ .

$\frac{3}{2}$	$2$	$- 3$	$- 24$	$76$	$- 60$
		$3$	$0$	$- 36$
	$2$	$0$	$- 24$

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.

$\frac{3}{2}$	$2$	$- 3$	$- 24$	$76$	$- 60$
		$3$	$0$	$- 36$
	$2$	$0$	$- 24$	$40$

Step 11

Multiply the newest entry in the result $(40)$ by the divisor $(\frac{3}{2})$ and place the result of $(60)$ under the next term in the dividend $(- 60)$ .

$\frac{3}{2}$	$2$	$- 3$	$- 24$	$76$	$- 60$
		$3$	$0$	$- 36$	$60$
	$2$	$0$	$- 24$	$40$

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.

$\frac{3}{2}$	$2$	$- 3$	$- 24$	$76$	$- 60$
		$3$	$0$	$- 36$	$60$
	$2$	$0$	$- 24$	$40$	$0$

Step 13

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

$(\frac{1}{2}) \cdot (2 x^{3} + 0 x^{2} + (- 24) x + 40)$

Step 14

Simplify the quotient polynomial.

$(\frac{1}{2}) \cdot (2 x^{3} - 24 x + 40)$
