Step-by-step explanation:

x= -2

the explanation is given below:

x2/4x-8

by definition, the nonpermissible replacement of x is the value that makes the denominator equal to zero.

keeping this on mind, you have :

-4x-8=0

-4x=8

x=8/-4

x=-2

x²/-4x-8=(-2)²/(-4)(-2)-8=4/8-8=4/0

Therefore, the x is -2

i.e,

x= -2
