Place your Numerator and denominator in parenthesis .
 
    ( 3 X^2 -1) /( X^2 -3X-18)  - ( X -2) / (X -6) =
 
     ( 3X^2 -1 ) / ( X -6) ( X +3)  - ( X - 2) / ( X -6 ) =
 
     ( 3X^2 -1 ) / ( X -6 ) ( X +3 )  -  ( X- 2 ) ( X +3 ) / ( X -6 ) ( X +3 ) =
 
        ( 3X^2 - 1 - X^2 - X +6 ) / ( X -6) ( X +3)=
 
         ( 2X^2 - X + 5 ) / ( X^2 - 3x - 18)
