Question

Solve the equation-
(x+1/x-1)-(x-1/x+1)​

Answer 1

Step-by-step explanation:

(x+1/x-1)-(x-1/x+1)

=[(x+1)^2-(x-1)^2]/(x)^2-(1)^2

=x^2+1+2x-x^2+1-2x/x^2-1

=2x^2+2/x^2-1

=2(x^2+1)/x^2-1

Answer 2

Answer:

x^2-4x+1

Step-by-step explanation:

(x+1)(x+1)/(x-1)(x+1)-(x-1)(x-1)/(x+1)(x-1)

(x^2+2x+1)/(x^2+1) - (x^2-2x+1)/(x^2+1)

x^2+2x+1-x^2+2x-1/x^2+1

4x/x^2+1

4x=-x^2-1

=x^2-4x+1
