We have to find the derivative of
(x+3)/(2x-5).
This can be done using the product rule which
states that the derivative of h(x) = f(x)* g(x) = f'(x)*g(x) + f(x)*g'(x) and the chain
rule
Take the given expression
(x+3)/(2x-5)
= (x+3)*(2x -
5)^-1
The derivative is (x +3)*(-1)*2*(2x - 5)^-2 + 1*(2x -
5)^-1
=> -2(x + 3)/ (2x - 5)^2 + 1/ (2x -
5)
=> [-2x - 6 + 2x - 5]/ (2x -
5)^2
=> -11 / (2x -
5)^2
The required result is -11 / (2x -
5)^2
