does anyone know a practicaly

way of finding results from

(4 - 3 x + {2 x}^{2} - x^{4}) \times (- 1 + {3 x}^{2} - x^{5}) ?

(4 - 3 x + {2 x}^{2} - x^{4}) . (- 1 + {3 x}^{2} - x^{5}) = ?

solution :

\begin{array}{cccccccc} 4 - 3 2 0 - 1 \\ - 1 0 3 0 0 - 1 \\ \times - 4 3 - 2 0 1 \\ 0 0 0 0 0 \\ 12 - 9 6 0 - 3 \\ 0 0 0 0 0 \\ 0 0 0 0 0 \\ - 4 3 - 2 0 1 \end{array}

the result is - 4 + 3 x + {10 x}^{2} - {9 x}^{3} + {6 x}^{4} - {4 x}^{5} - {2 x}^{7} + x^{9}
