$(z^{2} - z + 12) + (z^{3} + z^{2} - 12 z)$

Step 1

Remove parentheses.

$z^{2} - z + 12 + z^{3} + z^{2} - 12 z$

Step 2

Add $z^{2}$ and $z^{2}$ .

$2 z^{2} - z + 12 + z^{3} - 12 z$

Step 3

Subtract $12 z$ from $- z$ .

$2 z^{2} - 13 z + 12 + z^{3}$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
