Answer:
6x^3 +4x^2+4x-8 so D.
Step-by-step explanation:
Hey, this problem may look difficult but it is actually pretty easy. The (f-g)(x) is a tricky way of saying f(x)-g(x). So:
(2x^2 +4x-5)-(6x^3 -2x^2 +3)
First you distribute the negative sign
2x^2+4x-5-6x^3 +2x^2 -3
Then combine like terms
2x^2 + 2x^2 = 4x^2
6x^3 (Stays constant due to no like terms)
4x (Also stays constant due to no like terms)
-5-3= -8
So d.
Hope this helps
