Answer:
x³ - x² - 2
Explanation:
Pre-Solving
We are given the following two functions:
h(x) = 2x -2
g(x) = x³ - x³ - 2x
We want to find (h+g)(x).
Recall that (h+g)(x) is the same as h(x) + g(x).
This means we'll just simply add the two functions together.
Solving
(h+g)(x) = 2x - 2 + x³ - x² - 2x
Add like terms.
Rearrange:
x³ - x² + 2x - 2x - 2
This simplifies to:
x³ - x² - 2
