Hi! Can anyone help? I need to solve the following inequalitiy

$\displaystyle \frac{{3x}^{2 }-3x-5 }{{x}^{2 }-2x-3 } >3$

I rearrange the inequalitiy first into

$\displaystyle \frac{{3x}^{2 }-3x-5 }{{x}^{2}-2x-3 }-3>0 $

I the need to use the mulitiplication rule but am not sure what to multiply by...
