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 a constant times a function is the constant times the derivative of the function.
Apply the power rule: goes to
So, the result is:
The result is:
The result of the chain rule is:
Now simplify:
The answer is:
2 - 2*x ----------- 2 / 2 \ \x - 2*x/
/ 2\ | 4*(-1 + x) | 2*|-1 + -----------| \ x*(-2 + x)/ -------------------- 2 2 x *(-2 + x)
/ 2\ | 2*(-1 + x) | 24*|1 - -----------|*(-1 + x) \ x*(-2 + x)/ ----------------------------- 3 3 x *(-2 + x)
