Answer:
The simplified form of the given expression is [tex]7x^3-x-6[/tex].
Step-by-step explanation:
The given expression is
[tex](5x^3-5x-8)+(2x^3+4x+2)[/tex]
[tex]5x^3-5x-8+2x^3+4x+2[/tex]
Combine like terms,
[tex](5x^3+2x^3)+(-5x+4x)+(-8+2)[/tex]
[tex]7x^3+(-x)+(-6)[/tex]
[tex]7x^3-x-6[/tex]
Therefore the simplified form of the given expression is [tex]7x^3-x-6[/tex].
