Answer:

Step-by-step explanation:
Before adding the fractions we require them to have a common denominator.
Multiply the numerator/ denominator of the first fraction by 4
Multiply the numerator/ denominator of the second fraction by 3
+ 
Now add the numerators leaving the denominator
= 
= 
The correct answer is 3.25
(f-g)(x) is equivalent to f(x) - g(x)
So that would be (2x²-5) - (x²-4x-8) = 2x² - x² + 4x + 8 - 5 = x² + 4x + 3
Hope this helps.
