I'm stuck on what to do next Problem:H(s)=s/square root of s subtract 1 Differentiate using the Quotient Rule I got this far: (s^1/2-1)[s]-(s)[s^1/2-1]/(s^1/2)^2

I think he said $\displaystyle H(s)=\frac s{\sqrt{s-1}}$
is this what you mean? Yes
Well, in that case $\displaystyle \frac s{\sqrt s-1}=\frac{s\left(\sqrt s+1\right)}{s-1}$ Now apply the quotient rule.
