The question is to evaluate the quotient and remainder of the division using the long division method:

Step 1: Write out the problem in the long division format

Step 2: Divide the leading term of the dividend by the leading term of the divisor. Write down the calculated result in the upper part of the table. Multiply it by the divisor and subtract the dividend from the obtained result

$\begin{gathered} (-3x^3)/(x)=-3x^2 \\ -3x^2(x-3)=-3x^3+9x^2 \end{gathered}$

Step 3: Apply the steps from 2 above to the remainder at the bottom

$\begin{gathered} (4x^2)/(x)=4x \\ 4x(x-3)=4x^2-12x \end{gathered}$

Step 4: Apply the steps from 3 above

$\begin{gathered} (-2x)/(x)=-2 \\ -2(x-3)=-2x+6 \end{gathered}$

Step 5: Since the degree of the remainder is less than that of the divisor, we are done with the division. The quotient is the polynomial at the top and the remainder is at the bottom
