Answer:

Explanation:

f(x) = x² - 2x g(x) = x + 8

a) (f+g)(x) means add the 2 equations

(f+g)(x) = x² - 2x + x + 8

(f+g)(x) = x² - x + 8

b) (f-g)(x) means subtract the 2 equations

(f-g)(x) = ( x² - 2x) - (x + 8) >Distribute negative

(f-g)(x) = x² - 2x - x - 8

(f-g)(x) = x² - 3x - 8

c) (fg)(x) means multiply the 2 equations

(fg)(x) = (x² - 2x) (x + 8) >Foil

(fg)(x) = x³ + 8x² -2x²-16x

(fg)(x) = x³ + 6x² - 16x

d) (f/g)(x) means divide the 2 equations

(f/g)(x) = (x² - 2x)/(x + 8)
