Find Where Undefined/Discontinuous (10x)/(100x^2-10x)

$\frac{10 x}{100 x^{2} - 10 x}$

Step 1

Set the denominator in $\frac{10 x}{100 x^{2} - 10 x}$ equal to $0$ to find where the expression is undefined.

$100 x^{2} - 10 x = 0$

Step 2

Solve for $x$ .

Factor $10 x$ out of $100 x^{2} - 10 x$ .

Factor $10 x$ out of $100 x^{2}$ .

$10 x (10 x) - 10 x = 0$

Factor $10 x$ out of $- 10 x$ .

$10 x (10 x) + 10 x (- 1) = 0$

Factor $10 x$ out of $10 x (10 x) + 10 x (- 1)$ .

$10 x (10 x - 1) = 0$

If any individual factor on the left side of the equation is equal to $0$ , the entire expression will be equal to $0$ .

$x = 0$

$10 x - 1 = 0$

Set $x$ equal to $0$ .

$x = 0$

Set $10 x - 1$ equal to $0$ and solve for $x$ .

Set $10 x - 1$ equal to $0$ .

$10 x - 1 = 0$

Solve $10 x - 1 = 0$ for $x$ .

Add $1$ to both sides of the equation.

$10 x = 1$

Divide each term in $10 x = 1$ by $10$ and simplify.

Divide each term in $10 x = 1$ by $10$ .

$\frac{10 x}{10} = \frac{1}{10}$

Simplify the left side.

Cancel the common factor of $10$ .

Cancel the common factor.

$\frac{10 x}{10} = \frac{1}{10}$

Divide $x$ by $1$ .

$x = \frac{1}{10}$

The final solution is all the values that make $10 x (10 x - 1) = 0$ true.

$x = 0, \frac{1}{10}$

Step 3

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 $0$ .

$x = 0, x = \frac{1}{10}$

Step 4

Find Where Undefined/Discontinuous (10x)/(100x^2-10x)
