Step-by-step explanation:
Let's combine the like terms first, which are x^2 & -3x^2, and 3x & -4x.
x^2 -3x^2 is -2x^2. 3x -4x is -x.
The final, simplified expression would be -2x^2 -x.
Answer:
2h-3a
Step-by-step explanation:
First Find f(a+h)
f(a+h) =-a-h
Then find f(a)
f(a) =2a-3h
Then f(a+h) - f(a)= - a-h-(2a-3h)=2h-3a
