Differentiate term by term:
Apply the quotient rule, which is:
and .
To find :
The derivative of the constant is zero.
To find :
Apply the power rule: goes to
Now plug in to the quotient rule:
The derivative of a constant times a function is the constant times the derivative of the function.
Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
Apply the power rule: goes to
The result of the chain rule is:
So, the result is:
The result is:
Now simplify:
The answer is:
/ 5\ 4*|3 - -| \ x/ --------- 5 x
/ 2\ 60*|-1 + -| \ x/ ----------- 6 x
