Question

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

Answer 1

Answer:

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

Step-by-step 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   $1/(x+1)^{2}$
