expand (1,-2)y(1,-4)

Solution

expand

(1, - 2) y (1, - 4)

Solution

1 \cdot y, 1, - 1 \cdot y, 4 - 2 \cdot 1 \cdot y, 2 \cdot 4

Solution steps

(1, - 2) y (1, - 4)

= (1, - 2) (1, - 4) y

Expand

(1, - 2) (1, - 4) : 1, 1, - 1, 4 - 2 \cdot 1, 2 \cdot 4

= y (1, 1, - 1, 4 - 2 \cdot 1, 2 \cdot 4)

Expand

y (1, 1, - 1, 4 - 2 \cdot 1, 2 \cdot 4) : 1 \cdot y, 1, - 1 \cdot y, 4 - 2 \cdot 1 \cdot y, 2 \cdot 4

= 1 \cdot y, 1, - 1 \cdot y, 4 - 2 \cdot 1 \cdot y, 2 \cdot 4
