Find Where Undefined/Discontinuous -5/(12x)

$\frac{- 5}{12 x}$

Step 1

Set the denominator in $\frac{- 5}{12 x}$ equal to $0$ to find where the expression is undefined.

$12 x = 0$

Step 2

Divide each term in $12 x = 0$ by $12$ and simplify.

Divide each term in $12 x = 0$ by $12$ .

$\frac{12 x}{12} = \frac{0}{12}$

Simplify the left side.

Cancel the common factor of $12$ .

Cancel the common factor.

$\frac{12 x}{12} = \frac{0}{12}$

Divide $x$ by $1$ .

$x = \frac{0}{12}$

Simplify the right side.

Divide $0$ by $12$ .

$x = 0$
