1. suitable identity: x^2+(a+b)x+ab
                              =(100-5)(100 +3)
                             =100*100+(3-5)100+(3*-5)
                             =10000-200-15
                             =9785(verified)
2.suitable identity:(a+b)^2
   =(-a+c)^2
=-a^2+b^2+2*-a*b
=a^2  + b^2 -2ab

thnks for asking 
hope it helps
