Answer:
1. x^2 -2x + x+10 = x^2-x-10
2. x^2-3x -10
3. 11x^
3
−22x^
2
4. x-2/11
Step-by-step explanation:
f(x) x^2 -2x and g|(X) x + 10
1) f+g
f+g is f(x) + g(x) = x^2 -2x + x + 10 = x^2 -x -10 and you could write highest degree first if not already shown = x^2 -2x + x+10
2) f-g
f-g = f(x) = g(x) = x^2-2x - x+10 = x^2-3x -10
3) fg
fg = f (x) x g(x) = (x^2-2x) x (x+10) = 11x^
3
−22x^
2
4) f/g
f/g = f(x) / g(x) = x^2- 2x/11x = x-2/11
