Step 2.1

Factor $x$ out of $9 x$ .

$x^{2} + x \cdot 9 \frac{- 1}{x}$

Step 2.2

Cancel the common factor.

$x^{2} + x \cdot 9 \frac{- 1}{x}$

Step 2.3

Rewrite the expression.

$x^{2} + 9 \cdot - 1$

$x^{2} + 9 \cdot - 1$

Step 3

Multiply $9$ by $- 1$ .

$x^{2} - 9$

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