$(d^{2} + 6 d + 9) + (d^{3} + 6 d + 9)$

Step 1

Remove parentheses.

$d^{2} + 6 d + 9 + d^{3} + 6 d + 9$

Step 2

Add $6 d$ and $6 d$ .

$d^{2} + 12 d + 9 + d^{3} + 9$

Step 3

Add $9$ and $9$ .

$d^{2} + 12 d + d^{3} + 18$

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