Answer:

The simplified form of the given expression is 7x^3-x-6.

Step-by-step explanation:

The given expression is

(5x^3-5x-8)+(2x^3+4x+2)

5x^3-5x-8+2x^3+4x+2

Combine like terms,

(5x^3+2x^3)+(-5x+4x)+(-8+2)

7x^3+(-x)+(-6)

7x^3-x-6

Therefore the simplified form of the given expression is 7x^3-x-6.
