    Solve using Quotient Rule

    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

    is this what you mean?

    \frac d{ds} \frac {s}{\sqrt {s} - 1}

    I think he said

    H(s)=\frac s{\sqrt{s-1}}

    Well, in that case

    \frac s{\sqrt s-1}=\frac{s\left(\sqrt s+1\right)}{s-1}

    Now apply the quotient rule.
