Subtract. (3z^2 + 6z + 9) - (2z + 4) ______

Write down problem: First, write down the problem and distribute the negative sign to the terms inside the parentheses that are being subtracted. (3z^2 + 6z + 9) - (2z + 4) = 3z^2 + 6z + 9 - 2z - 4Group like terms: Next, group the like terms together. In this case, we can group the z terms and the constant terms. 3z^2 + (6z - 2z) + (9 - 4)Perform subtraction: Now, perform the subtraction for the like terms. 3z^2 + 4z + 5

Q. Subtract.

\newline

(3z^2 + 6z + 9) - (2z + 4)

Write down problem: First, write down the problem and distribute the negative sign to the terms inside the parentheses that are being subtracted. $\newline$ $(3z^2 + 6z + 9) - (2z + 4) = 3z^2 + 6z + 9 - 2z - 4$
Group like terms: Next, group the like terms together. In this case, we can group the $z$ terms and the constant terms. $3z^2 + (6z - 2z) + (9 - 4)$
Perform subtraction: Now, perform the subtraction for the like terms. $3z^2 + 4z + 5$
