(2n^2 + 9n + 8) + (9n^2 + 5n + 8)

\newline

______

Combine like terms: Combine like terms by adding the coefficients of the terms with the same degree. $\newline$ $(2n^2 + 9n + 8) + (9n^2 + 5n + 8) = (2n^2 + 9n^2) + (9n + 5n) + (8 + 8)$
Perform addition of coefficients: Perform the addition of the coefficients. $\newline$ $(2n^2 + 9n^2) + (9n + 5n) + (8 + 8) = 11n^2 + 14n + 16$
