Answer:

The simplified answer is
1/(x+1)^(2)

Explanation:

For the given expression: (− 1/x )× 1−x/1+x × x/x^2−1

we need to simplify it


x^(2) -1 = (x+1)×(x-1)

eliminating x and x-1 from the given equation we get


1/(x+1)^(2)

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
1/(x+1)^(2)
