(x+1/x-1)^2
If x is not equal to 0 and is not equal to 1, and if x is replaced by 1/x everywhere in the expression above, then the resulting expression is equivalent to:
(A) (x+1/x-1)^2
(B) (x-1/x+1)^2
(C) x^2+1/1-x^2
(D) x^2-1/x^2+1
(E) -(x-1/x+1)^2
If x is not equal to 0 and is not equal to 1, and if x is replaced by 1/x everywhere in the expression above, then the resulting expression is equivalent to:

(B) (x-1/x+1)^2
(C) x^2+1/1-x^2
(D) x^2-1/x^2+1
(E) -(x-1/x+1)^2
