$\frac{2 x}{x + 14} + \frac{x + 14}{x - 14}$

Step 1

Set the denominator in $\frac{2 x}{x + 14}$ equal to $0$ to find where the expression is undefined.

$x + 14 = 0$

Step 2

Subtract $14$ from both sides of the equation.

$x = - 14$

Step 3

Set the denominator in $\frac{x + 14}{x - 14}$ equal to $0$ to find where the expression is undefined.

$x - 14 = 0$

Step 4

Add $14$ to both sides of the equation.

$x = 14$

Step 5

The equation is undefined where the denominator equals $0$ , the argument of a square root is less than $0$ , or the argument of a logarithm is less than or equal to $0$ .

$x = - 14, x = 14$
