Solve using long division.

Mkey [24]

Answer:

Quotient is $3x-5$ and remainder is 0.

Step-by-step explanation:

Given:

Dividend = $3x^2+7x-20$

Divisor = $x+4$

The long division is shown in the attachment.

Step 1: we need to divide $3x^2+7x-20$ with $x+4$ we first multiply $x+4$ with 3x we get the remainder as $-5x-20$

Quotient as 3x.

Step 2: Now the dividend is $-5x-20$ and divisor $x+4$ now we will multiply $x+4$ with -5 we get the remainder as 0 and Quotient as $3x-5$

Hence Quotient is $3x-5$ and remainder is 0.
