Some Standard Algebraic Identities list are given below:

  • Identity 1: a+b2 = a2 + 2ab + b2

  • Identity II: a-b2=a2 - 2ab + b2

  • Identity III: a2b2=a+ba-b

  • Identity IV: x+ax+b = x2 + a+b x + ab

  • Identity V: a+b+c2= a2 + b2 + c2 + 2ab + 2bc +2ca

  • Identity Vl: a+b3 = a3 + b3 + 3ab a+b

  • Identity VII: a-b3=a3-b3-3ab a-b

  • Identity VIII: a3 + b3 + c3-3abc = a+b+c(a2 + b2 + c2-ab-bc-ca)
