Answer:
The simplified answer is
Explanation:
For the given expression: (− 1/x )× 1−x/1+x × x/x^2−1
we need to simplify it
= (x+1)×(x-1)
eliminating x and x-1 from the given equation we get
The value of x can't be zero
As we can't divide zero by zero
The value of x can't be one
As we can't divide zero by zero
The simplified answer is
