According to the problem, the expressions are


\begin{gathered} 4x^3+11x^2+13x+19 \\ x+2 \end{gathered}

To develop a long division solution, we solve as follows

As you can observe in the division above, the division is no exact with a reminder of 5.

Now, we use the division algorithm to express the result


\frac{\text{Dividend}}{\text{Divisior}}=quotient+\frac{re\min der}{\text{Divisor}}

Hence, the answer is


(4x^3+11x^2+13x+19)/(x+2)=4x^2+3x+7+(5)/(x+2)
