Which of the following gives the derivative of f(x)g(x)\dfrac{f(x)}{g(x)} where ff and gg are differentiable and g(x)≠0g(x)\neq 0? (a) f′(x)g(x)+f(x)g′(x)[g(x)]2\dfrac{f'(x)g(x)+f(x)g'(x)}{[g(x)]^{2}} (b) f′(x)g′(x)\dfrac{f'(x)}{g'(x)} (c) f′(x)g(x)−f(x)g′(x)[g(x)]2\dfrac{f'(x)g(x)-f(x)g'(x)}{[g(x)]^{2}} (d) f′(x)g(x)−f(x)g′(x)g(x)\dfrac{f'(x)g(x)-f(x)g'(x)}{g(x)}
