Step 1.1

Move the limit inside the absolute value signs.

$\frac{| lim_{x \to - 2} x + 2 |}{x + 2}$

Step 1.2

Split the limit using the Sum of Limits Rule on the limit as $x$ approaches $- 2$ .

$\frac{| lim_{x \to - 2} x + lim_{x \to - 2} 2 |}{x + 2}$

Step 1.3

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

$\frac{| lim_{x \to - 2} x + 2 |}{x + 2}$

Step 2

Evaluate the limit of $x$ by plugging in $- 2$ for $x$ .

$\frac{| - 2 + 2 |}{x + 2}$

Step 3.1.1

Add $- 2$ and $2$ .

$\frac{| 0 |}{x + 2}$

Step 3.1.2

The absolute value is the distance between a number and zero. The distance between $0$ and $0$ is $0$ .

$\frac{0}{x + 2}$

Step 3.2

Divide $0$ by $x + 2$ .

$0$
