    j*omega = s

    so for a, i got Vo = Vi * (sL/(sL+R+1/sc))
    so H(s) = sL/(sL+R+1/sc) and i multiplied it by s/s to get rid of s in in denominator of the 1/sc term to get s^2*L/(s^2*L+Rs+1/c)

    is this correct?

    for the second one i got Vo=Vi*(1/sc)/(R*sL/R+sL)+1/sc. i did a similar thing by multiplying by s/s.

    any suggestions would be appreciated.

    that looks right to me. Only you need to match parenthesis carefully.

    [tex]H(s) = \frac{sL}{sL+R+\frac{1}{sC}}[/tex]
