f(X) = 9x^3 + 2x^2 - 5x^3 - 7x + 4 and g(X) = 5x^3 - 7x + 4. what is f(X) - g(X)? Show all of your steps and write your final answer in factored form. Please! brainly answers garenteed !!! 50 pts!!!

Respuesta :

The answer is simple. Since g(x) is already in the equation 9x^3+2x^2, we know that if fg(x))-g(x) must equal f(x). If x-x=0, then 5x^3-7x+4-5x^3-7x+4. Yet if we simplify, we have the answer 8. So your final answer will be 9x^3+2x^2+8.
Let's solve for f(x).
f(x)=9x^3+2x^25x^37x+4Divide both sides by x:
f(x)/x=4x^3+2x^2−7x+4/x
f=4x^3+2x^2−7x+4/x
To solve for g(x).
g(x)=5x^37x+4Step 1: Divide both sides by x.g(x)/x=5x^37x+4xg=5x^37x+4xAnswer:g=5x^37x+4/x

I really hope this helps!!:)
