Find Where Undefined/Discontinuous 12/(19x)

$\frac{12}{19 x}$

Step 1

Set the denominator in $\frac{12}{19 x}$ equal to $0$ to find where the expression is undefined.

$19 x = 0$

Step 2

Divide each term in $19 x = 0$ by $19$ and simplify.

Divide each term in $19 x = 0$ by $19$ .

$\frac{19 x}{19} = \frac{0}{19}$

Simplify the left side.

Cancel the common factor of $19$ .

Cancel the common factor.

$\frac{19 x}{19} = \frac{0}{19}$

Divide $x$ by $1$ .

$x = \frac{0}{19}$

Simplify the right side.

Divide $0$ by $19$ .

$x = 0$
