I have no idea how to even start on this!

f(x)=9x^3+2x^2-5x+4 and g(x)=5x^3-7x+4. What is f(x)-g(x)? Show all of your steps and wrote your final answer in factored form.

If someone could help me work through this problem that would be great!

1. for heavens sake it says to subtract, so subtract

9-5 = 4
2 - 0 = 2
-5 - -7 = 2
4-4 = 0
so

4 x^3 + 2 x^2 + 2 x

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