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
