Find Where Undefined/Discontinuous 12/(22x)

$\frac{12}{22 x}$

Step 1

Set the denominator in $\frac{12}{22 x}$ equal to $0$ to find where the expression is undefined.

$22 x = 0$

Step 2

Divide each term in $22 x = 0$ by $22$ and simplify.

Divide each term in $22 x = 0$ by $22$ .

$\frac{22 x}{22} = \frac{0}{22}$

Simplify the left side.

Cancel the common factor of $22$ .

Cancel the common factor.

$\frac{22 x}{22} = \frac{0}{22}$

Divide $x$ by $1$ .

$x = \frac{0}{22}$

Simplify the right side.

Divide $0$ by $22$ .

$x = 0$
