$\frac{lim_{x \to 0} \sqrt{2 - x} - \sqrt{2}}{x}$

Step 1

Split the limit using the Sum of Limits Rule on the limit as $x$ approaches $0$ .

$\frac{lim_{x \to 0} \sqrt{2 - x} - lim_{x \to 0} \sqrt{2}}{x}$

Step 2

Move the limit under the radical sign.

$\frac{\sqrt{lim_{x \to 0} 2 - x} - lim_{x \to 0} \sqrt{2}}{x}$

Step 3

Split the limit using the Sum of Limits Rule on the limit as $x$ approaches $0$ .

$\frac{\sqrt{lim_{x \to 0} 2 - lim_{x \to 0} x} - lim_{x \to 0} \sqrt{2}}{x}$

Step 4

Evaluate the limit of $2$ which is constant as $x$ approaches $0$ .

$\frac{\sqrt{2 - lim_{x \to 0} x} - lim_{x \to 0} \sqrt{2}}{x}$

Step 5

Evaluate the limit of $\sqrt{2}$ which is constant as $x$ approaches $0$ .

$\frac{\sqrt{2 - lim_{x \to 0} x} - \sqrt{2}}{x}$
