(Picture) MULTIPLYING POLYNOMIALS AND SIMPLIFYING EXPRESSIONS PLEASE HELP!!!!

Answer:
[tex]x^3+5x^2+5x-2[/tex]
Step-by-step explanation:
x^3+3x^2-x+2x^2+6x-2
To simplify this expression completely we combine like terms
3x^2 and 2x^2 are like terms
3x^2 + 2x^2 is 5x^2
-x and 6x are like terms
-1x + 6x is 5x
[tex]x^3+3x^2-x+2x^2+6x-2[/tex]
[tex]x^3+5x^2+5x-2[/tex]
We cannot simplify more because all terms are unlike terms.
