Given:-

expanded from of (2a+6b)²

To solve the we use an identity what is (a+b)²

expanded form of (a+b)²=a²+2ab+b²

similarly we solve the sum (2a+6b)²

(2a+6b)²

=(2a)²+2×2a×6b+(6b)²

=4a²+2×12ab+36b²

=4a²+24ab+36b²

The algebraic equations which are valid for all values of variables in them are called algebraic identities. They are also used for the factorization of polynomials. In this way, algebraic identities are used in the computation of algebraic expressions and solving different polynomials. You have already learned about a few of them in the junior grades. In this article, we will recall them and introduce you to some more standard algebraic
