Answer:

Identity I =(a+b)2 = a2+2ab+b2

Identity II =(a-b)2 = a2- 2ab+b2

Identity III =a2-b2= (a+b) (a-b)

Identity IV =(x+a) (x+b) = x2+(a+b) x+ab

Identity V =(a+b+c)2= a2+b2+c2+ 2ab+2bc+2ca

Identity VI

(a+b)3= a3+b3+3ab(a+b)

Identity VII =(a-b)3= a3 -b3-3ab(a-b)

Identity VIII =a3 +b3+c3-3abc
