simplify the expression. if not possible, write simplified.
5z² + 3z + 8z²
16²

Explanation:

Step1: Combine like - terms

Combine the terms with the same variable and exponent. The like - terms here are $5z^{2}$ and $8z^{2}$.
$5z^{2}+8z^{2}+3z$

Step2: Add the coefficients of like - terms

The coefficients of $z^{2}$ are 5 and 8. Add them together: $(5 + 8)z^{2}+3z$.
$13z^{2}+3z$

Answer:

$13z^{2}+3z$
