    You need to differentiate both sides of: \[f(x)=-h(x)-\frac{x}{h(x)}\]

    \[(f(x))'=f'(x)\] \[(-h(x)-\frac{x}{h(x)})'=(-h(x))'-(\frac{x}{h(x)})'=-(h(x))'-(\frac{x}{h(x)})'\] I used the constant multiple rule to bring out -1 and just look at differentiating h(x) Now I will leave the quotient rule to you: Your job is to find: \[(\frac{x}{h(x)})'\]
