List of Algebraic Identities 
 Algebraic Identities  An identity is an equation that stays true regardless of the values assigned to its variables. It can be used to simplify or rearrange algebraic equations, as both sides of an identity are interchangeable and can be substituted for each other at any time.
 List of Algebraic Identities  There is a wide variety of identities due to the fact that the terms used in identity can be altered slightly and transformed into other identities.
Identity I : (x+y)2 = x2+2xy+y2
Identity II : (xy)2 = x22xy+y2
Identity III : x2y2=(x+y)(xy)
Identity IV : (x+a)(x+b)=x2+(a+b)x+ab
Identity V : (x+y+z)=x2+y2+z2+2xy+2yz+2zx
Identity VI : (x+y)3=x3+y3+3xy(x+y)
Identity VII : (xy)3=x3y33xy(xy)
=x33x2y+3xy2y3
Identity VIII : x3+y3+z33xyz=(x+y+z)(x2+y2+z2xyyzzx)
