Find [g•h] (x) and [h•g] (x) g (x) = 2x h (x) = -10x-10

-40x (x+1)

Step-by-step explanation:

Find [g•h] (x) and [h•g] (x)

g (x) = 2x

h (x) = -10x-10

[g•h] (x) = 2x (-10x-10) = - 20x^2-20x = - 20x (x+1)

[h•g] (x) = (-10x-10) 2x = - 10x (2x) - 10 (2x) = - 20x^2-20x

[g•h] (x) and [h•g] (x)

and means addition

-20x^2-20x + (-20x^2-20x)

-20x^2-20x-20x^2-20x

choose like terms

-20x^2-20x^2-20x-20x

-40x^2-40x

-40x (x+1)
