Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
Differentiate term by term:
Apply the power rule: goes to
The derivative of the constant is zero.
The result is:
The result of the chain rule is:
Now simplify:
The answer is:
-1 ------------- 3/2 4*(-1 + x)
3 ------------- 5/2 8*(-1 + x)
