Step 2.1

Factor $- 1$ out of $- 2 x^{2}$ .

$- (2 x^{2}) - x - 15$

Step 2.2

Factor $- 1$ out of $- x$ .

$- (2 x^{2}) - (x) - 15$

Step 2.3

Rewrite $- 15$ as $- 1 (15)$ .

$- (2 x^{2}) - (x) - 1 (15)$

Step 2.4

Factor $- 1$ out of $- (2 x^{2}) - (x)$ .

$- (2 x^{2} + x) - 1 (15)$

Step 2.5

Factor $- 1$ out of $- (2 x^{2} + x) - 1 (15)$ .

$- (2 x^{2} + x + 15)$

$- (2 x^{2} + x + 15)$

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