Question

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

Answer 1

`x^3+5x^2+5x-2`

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

`x^3+3x^2-x+2x^2+6x-2`

`x^3+5x^2+5x-2`

We cannot simplify more because all terms are unlike terms.
