Question

For what value of x is the rational expression below undefined?

Answer 1

The answer is a.Good luck

Answer 2

Answer:  The correct option is (A) 6.

Step-by-step explanation:  We are given to select the value of x for which the following rational expression become undefined :

$E=\dfrac{3x-5}{x-6}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

We know that

a rational expression become undefined when the denominator is equal to zero.

Therefore, the rational expression (i) will become undefined when

$x-6=0\\\\\Rightarrow x=6.$

Thus, the required value of x for which the given rational expression become undefined is 6.

Option (A) is CORRECT.
