    $\begin{array}{c|c}\qquad \quad x^3 – 2x^2 – 7&x + 1\\\hline x^3 + x^2&x^2 – 3x – 3\\\text{______________________}\\-3x^2 – 7\\-3x^2 – 3x\\\text{______________________}\\-3x – 7\\-3x-3\\\text{______________________}\\-4\end{array}$
    $\text{Vậy}$ (x^3 – 2x^2 – 7) : (x + 1) = x^2 – 3 – 3 $\text{(dư}$ -4)
