展開する (5,-4,3)x(2,3,-4)

解

展開する

(5, - 4, 3) x (2, 3, - 4)

5 x, 2, 3, - 5 x, 4 - 4 x, 3 \cdot 2, 3, 4, 3 \cdot 4

解答ステップ

(5, - 4, 3) x (2, 3, - 4)

= (5, - 4 \cdot 3,) (2 \cdot 3,, - 4) x

拡張

(5, - 4, 3) (2, 3, - 4) : 5, 2, 3, - 5, 4 - 4, 3 \cdot 2, 3, 4, 3 \cdot 4

= x (5, 2, 3, - 5, 4 - 4, 3 \cdot 2, 3, 4, 3 \cdot 4)

拡張

x (5, 2, 3, - 5, 4 - 4, 3 \cdot 2, 3, 4, 3 \cdot 4) : 5 x, 2, 3, - 5 x, 4 - 4 x, 3 \cdot 2, 3, 4, 3 \cdot 4

= 5 x, 2, 3, - 5 x, 4 - 4 x, 3 \cdot 2, 3, 4, 3 \cdot 4
