Divide (4x-8)/(4x+20)

$\frac{4 x - 8}{4 x + 20}$

Step 1

Set up the polynomials to be divided. If there is not a term for every exponent, insert one with a value of $0$ .

$4 x$

$20$

$4 x$

$8$

Step 2

Divide the highest order term in the dividend $4 x$ by the highest order term in divisor $4 x$ .

					$1$
	$4 x$	+	$20$		$4 x$	-	$8$

Step 3

Multiply the new quotient term by the divisor.

Step 4

The expression needs to be subtracted from the dividend, so change all the signs in $4 x + 20$

Step 5

After changing the signs, add the last dividend from the multiplied polynomial to find the new dividend.

Step 6

The final answer is the quotient plus the remainder over the divisor.

$1 - \frac{28}{4 x + 20}$
