Example: e²+7e-11/e-2 + 3-5e/e-2=first is copy the numerator and u add the like terms
            u copy the e²  7e+(-5e)=2e then,3-11=8
          e²+2e+8   =   (e+4)(e-2)  
          ^          ^             e-2        u cancelled the e-2 because the same and the answer is
      e  e       +4 -2                          =e+4
