Add. (3z^2 + 3z + 9) + (7z + 6) ______

Identify like terms: Identify the like terms in both polynomials and write them down together. (3z^2 + 3z + 9) + (7z + 6) = 3z^2 + (3z + 7z) + (9 + 6)Combine like terms: Combine the like terms, which are the terms with the same variable and exponent. 3z^2 + (3z + 7z) + (9 + 6) = 3z^2 + 10z + 15

\newline

(3z^2 + 3z + 9) + (7z + 6)

\newline

______

Identify like terms: Identify the like terms in both polynomials and write them down together. $\newline$ $(3z^2 + 3z + 9) + (7z + 6) = 3z^2 + (3z + 7z) + (9 + 6)$
Combine like terms: Combine the like terms, which are the terms with the same variable and exponent. $3z^2 + (3z + 7z) + (9 + 6) = 3z^2 + 10z + 15$
