Question

Hi, I have utterly no idea what I’m doing here.
f(x)=9×3+2×2−5x+4 and g(x)+5×3−7x+4. what is f(x)−g(x)?
Show all of your steps and write your final answer in factored form.

I am so utterly confused right now. Help.

    Answer:

    2x(4x^2+x+1)

    Step-by-step explanation:

    f(x) = 9x^3 + 2x^2 – 5x + 4

    g(x) = 5x^3 +0x^2 – 7x + 4

    f(x) – g(x) =

    =(9x^3-5x^3) + (2x^2-0x^2) + (-5x – (-7x)) + (4-4) = 4x^3 +2x^2 +2x

    =2x(4x^2+x+1)
