Answer:
-x^3 + 3x^2 - 6x + 8
Explanation:
To solve this, first distribute the negative to everything inside the 2nd set of ( ). Here's what your problem will look like after distributing:
x^3 - 2x + 5 - 2x^3 + 3x^2 - 4x + 3
Now all you need to do is combine like terms. Here's a list of the terms you can combine:
x^3 and -2x^3
-2x and -4x
5 and 3
Here's what your equation will look like after combining all like terms:
-x^3 + 3x^2 - 6x + 8
This is your final answer.
