Question

Second Derivative of (2x^3+2x^2-12x)/(x^3+x^2-12x). I keep getting 24(-5x^4+6x^3-20x^2-24x-156)/(x^2+x-12)^4

Answer 1

is the first eqn the first dervative? or original eqn?

Answer 2

The first equation in in the original format.

Answer 3

Which I got= (-12(2x+1)/((x^2+x-12)^2)

Answer 4

for the first derivative

Answer 5

i got 24(3x^2+3x+13)/(x^2+x-12)^3
2nd deriv

Answer 6

that or my calcumilator is lying
