if you have thought hence :     a + 2b     -a - 2b
                                       (-) ------ = --------  so but if you have thought in this 
                                             2x-y         2x-y                                           

way          -a+2b
          (+) ------   and now this sign (+) will be changed in (-) the fraction will be  
                 2x-y  

(-)(-a+2b)      a-2b
 --------- = -------
   2x-y             2x-y
