Detail solution
-
The derivative of a constant times a function is the constant times the derivative of the function.
-
Apply the quotient rule, which is:
and .
To find :
-
Apply the power rule: goes to
To find :
-
The derivative of is .
Now plug in to the quotient rule:
-
So, the result is:
-
The answer is:
