first derivative=
(x^2 -16)(4x) - (2x^2 -8)(x) / (x^2 -16)^2 ....
simplified = (2x^3 -72x) / (x^4 -32x^2 + 256)
second derivative =
(x^4 -32x^2 + 256)(6x^2 -72) - (2x^3 -72x)(4x^3 -64x) / (x^4 -32x^2 + 256)
yep so that big huge answer is what i got. it can be simplifed some more if you feel like it :)
