Question difference between quotient rule and product rule
Product rule : $$\frac{d}{dx} f(x)g(x)=f'(x)g(x)+f(x)g' (x)$$ Quotient rule : $$\frac{d}{dx} \frac{f(x)}{g(x)}=\frac{f'(x)g(x)-f(x)g'(x)}{[g(x)]^2}$$ Suppose, the following is given in question. $$y=\frac{2x^3+4x^2+2}{3x^2+2x^3}$$ Simply, this is looking like Quotient rule. But, if I...
