Apply the quotient rule, which is:
and .
To find :
Differentiate term by term:
The derivative of the constant is zero.
Apply the power rule: goes to
The result is:
To find :
Differentiate term by term:
The derivative of the constant is zero.
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:
Now plug in to the quotient rule:
The answer is:
1 2*(x - 3) ------- - ---------- 2*x + 7 2 (2*x + 7)
/ 2*(-3 + x)\ 4*|-1 + ----------| \ 7 + 2*x / ------------------- 2 (7 + 2*x)
/ 2*(-3 + x)\ 24*|1 - ----------| \ 7 + 2*x / ------------------- 3 (7 + 2*x)
