expand (1,-2)*(x,y)

Solution

expand

(1, - 2) \cdot (x, y)

Solution

1 \cdot (, x y), - 2 (, x y)

Solution steps

(1, - 2) (x, y)

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

Apply the distributive law:

a (b - c) = ab - a c

a = (x, y), b = 1,, c = 2

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

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