Answer:

-3x - 2y + 9z

Explanation:

Since you are adding two polynomials, the parentheses are unnecessary, so you can just drop them. Then combine like terms. Like terms are terms that have the same variable part such as 6z and 3z.

(6z - 4y + 2x) + (3z - 5x + 2y) = Original problem.

= 6z - 4y + 2x + 3z - 5x + 2y Drop unnecessary parentheses.

= 2x - 5x - 4y + 2y + 6z + 3z Rearrange terms to group like terms.

= -3x - 2y + 9z Combine each set of like terms.

Answer: -3x - 2y + 9z
