Add. (z^2 + 4z + 9) + (z^2 + 5z) ______

Write Problem: Write down the problem. (z^2 + 4z + 9) + (z^2 + 5z) We need to combine like terms to simplify the expression.Combine Terms: Combine the like terms. (z^2 + z^2) + (4z + 5z) + 9 Add the coefficients of the like terms.Add Coefficients: Perform the addition. (z^2 + z^2) = 2z^2 (4z + 5z) = 9z So, 2z^2 + 9z + 9

\newline

______

Write Problem: Write down the problem. $\newline$ egin{equation}(z^ $2$ + $4$ z + $9$ ) + (z^ $2$ + $5$ z) $\newline$ ext{We need to combine like terms to simplify the expression.} $\newline$ egin{equation}
Combine Terms: Combine the like terms. $\newline$ $(z^2 + z^2) + (4z + 5z) + 9$ $\newline$ Add the coefficients of the like terms.
Add Coefficients: Perform the addition. $\newline$ $(z^2 + z^2) = 2z^2$ $\newline$ $(4z + 5z) = 9z$ $\newline$ So, $2z^2 + 9z + 9$
