Answer D.)
Step-by-step explanation: becaues you KCF when dividing fractions
 
        
                    
             
        
        
        
I'm assuming you want to solve for  z  :)
By simplifying both sides of the equation, then isolating the variable.
Exact form:
z= -5/3 , - 11/3
Mixed number form:
z=  −1  2/3  ,  −3  2/3
 
        
                    
             
        
        
        
Answer:  (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.
