    It depends on what the GCF is

    its a wrong differentation, but look at the arrow part , I factored the negative sign of the GCF in order to eliminate the GCF and the denominator

    Before the arrow and after the arrow, the expressions are not equal.

    You have to cancel out 1 (x^2+1) in the denominator when you cancel 1 in the numerator.

    Before the arrow, you have 2x(x^2−1) etc. To take out a negative, you'd end up with: -2x(1 - x^2)

    \(x^2 - 1 = -(1 - x^2)\ne -(x^2 + 1)\)
