$\frac{\sqrt{9 x + h} - \sqrt{9 x}}{h}$

Step 1

Rewrite $9$ as $3^{2}$ .

$\frac{\sqrt{9 x + h} - \sqrt{3^{2} x}}{h}$

Step 2

Pull terms out from under the radical.

$\frac{\sqrt{9 x + h} - (3 \sqrt{x})}{h}$

Step 3

Multiply $3$ by $- 1$ .

$\frac{\sqrt{9 x + h} - 3 \sqrt{x}}{h}$

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