$2 {(3 x)}^{2} + 18 (3 x) - 14$

Step 1

Apply the product rule to $3 x$ .

$2 (3^{2} x^{2}) + 18 (3 x) - 14$

Step 2

Raise $3$ to the power of $2$ .

$2 (9 x^{2}) + 18 (3 x) - 14$

Step 3

Multiply $9$ by $2$ .

$18 x^{2} + 18 (3 x) - 14$

Step 4

Multiply $3$ by $18$ .

$18 x^{2} + 54 x - 14$

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