Find the second derivative of x(x+1)^3

4 answers

have you found the first derivative?
yes, I think I found the second too. 6(x+1)(2x+1)?
x(x+1)^3

1st derivative
(x)*3(x + 1)^2*(1) + (x + 1)^3 * (1)
3x(x + 1)^2 + (x + 1)^3

Is this what you have for the 1st derivative?

I'm not a tutor, just a helper, but I've checked my answer twice.
Allison , you are right,
it is 6(x+1)(2x+1) after factoring and simplifying.

Helper is correct too.
