= (3, - 2 \cdot 1,) (6 \cdot 1,, - 2) A B

Expand

(3, - 2, 1) (6, 1, - 2) : 3, 6, 1, - 3, 2 - 2, 1 \cdot 6, 1, 2, 1 \cdot 2

= A B (3, 6, 1, - 3, 2 - 2, 1 \cdot 6, 1, 2, 1 \cdot 2)

Expand

A B (3, 6, 1, - 3, 2 - 2, 1 \cdot 6, 1, 2, 1 \cdot 2) : 3 A B, 6, 1, - 3 A B, 2 - 2 A B, 1 \cdot 6, 1, 2, 1 \cdot 2

= 3 A B, 6, 1, - 3 A B, 2 - 2 A B, 1 \cdot 6, 1, 2, 1 \cdot 2
