$f (x) = \frac{x + 7}{2 x^{2} - 14}$

Step 1

Set $\frac{x + 7}{2 x^{2} - 14}$ equal to $0$ .

$\frac{x + 7}{2 x^{2} - 14} = 0$

Step 2

Solve for $x$ .

Step 2.1

Set the numerator equal to zero.

$x + 7 = 0$

Step 2.2

Subtract $7$ from both sides of the equation.

$x = - 7$

$x = - 7$

Step 3

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