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