Answer:

$-3x^3+x$

Step-by-step explanation:

Let's first write the expression:

$-3x+x^3-2x^2-(4x^3-2x^2-4x)$

Now we can simplify. Be sure to remember to distribute the "-" to all the numbers in the parentheses. You can picture it like multiply "-1" to all the numbers in the parentheses to make it easier.

$-3x+x^3-2x^2-4x^3+2x^2+4x$
