Question

For what value of x is the rational expression below undefined x-4/4 x

Answer 1

The value of X that will make this rational expression undefined would be if X = 0.

Answer 2

Answer:

$x=0$

Step-by-step explanation:

We have been an rational expression $\frac{x-4}{4x}$. We are asked to find the value of x for which our given expression is undefined.

We know that a rational expression is undefined when its denominator becomes zero. So find such value of x for our given expression, we will equate denominator with 0 and solve for c as:

$4x=0$

$\frac{4x}{4}=\frac{0}{4}$

$x=0$

Therefore, when x is equal to 0 our given expression will be undefined.
