$- x^{2} - 2 x + 9$

Step 1

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

$- (x^{2}) - 2 x + 9$

Step 2

Factor $- 1$ out of $- 2 x$ .

$- (x^{2}) - (2 x) + 9$

Step 3

Rewrite $9$ as $- 1 (- 9)$ .

$- (x^{2}) - (2 x) - 1 (- 9)$

Step 4

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

$- (x^{2} + 2 x) - 1 (- 9)$

Step 5

Factor $- 1$ out of $- (x^{2} + 2 x) - 1 (- 9)$ .

$- (x^{2} + 2 x - 9)$

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