  # Concise Selina Solutions for Class 8 maths Chapter 12 Algebraic Identities

An algebraic identity is an equality that holds for any values of its variables. For example, the identity (x+y)^2 = x^2 + 2xy + y^2 holds for all values of x and y. Maths is a base of everything, and Algebraic Identities are an essential part of it. Suppose you want to multiply two large numbers 995 and 1008. Then, it will take a lot of time if you multiply through the multiplication process. But if you know the Algebraic Identities, then you can quickly solve it without much effort. Similarly, many everyday situations can be modelled into mathematical equations. The algebraic identities provide the simplest way to factorise such equations. As per the definition, an algebraic identity is an equality that holds for any values of its variables. By putting the values of the respective coefficient and variables in the given identity, you will get the answer. If you know the identities well, then you can use them to simplify many things. So, go through this chapter in-depth and solve all the questions of this chapter.
