expand A(-13,-15)yB(5,-19)

expand

A (- 13, - 15) y B (5, - 19)

- 13 A y B, 5, 13, 19 - 15 \cdot 5 A y B, 15 \cdot 19

Solution steps

A (- 13, - 15) y B (5, - 19)

= (- 13, - 15) (5, - 19) A y B

Expand

(- 13, - 15) (5, - 19) : - 13, 5, 13, 19 - 15 \cdot 5, 15 \cdot 19

= A y B (- 13, 5, 13, 19 - 15 \cdot 5, 15 \cdot 19)

Expand

A y B (- 13, 5, 13, 19 - 15 \cdot 5, 15 \cdot 19) : - 13 A y B, 5, 13, 19 - 15 \cdot 5 A y B, 15 \cdot 19

= - 13 A y B, 5, 13, 19 - 15 \cdot 5 A y B, 15 \cdot 19
