Answer:

4hx - 6h

Step-by-step explanation:

Given

f(x) = x^2 - 3x

Simply

f(x + h) - f(x - h)

Solution

f(x + h) - f(x - h) =
(x + h)^2 - 3(x + h) - (x - h)^2 + 3(x - h) =
x^2 + 2hx + h^2 - 3x - 3h - x^2 + 2hx - h^2 + 3x - 3h =
(x^2 - x^2) + (2hx + 2hx) - (3x - 3x) + (h^2 - h^2) - (3h + 3h) =
4hx - 6h
