Class 8 Maths Chapter 9 Algebraic Expressions and Identities all exercises in English Medium as well as Hindi Medium are given below to download in PDF form. All the solutions are done properly considering the latest CBSE Syllabus 2021-22.

In Chapter 9 Algebraic Expression and Identities, we have to learn about the fundamental terms like factors, coefficients, monomial, binomial, trinomial and all other polynomials, like and unlike terms in an algebraic expression, additions and subtractions of expressions taking like terms aside. Multiplications of two or three monomial and the multiplication of a monomial or binomial with a polynomial. Simplification of different polynomials using various identities. The following are the some standard identities:
1. (a – b)² = a² – 2ab + b²
2. (a + b)² = a² + 2ab + b²
3. (a + b)(a – b) = a² – b²

In order to factorize or simplify any algebraic expression, common identities are required. Taking common helps to make the factors of expressions and simplify the factors of two. To understand the algebraic expression in the simplest form, we must remember almost all the identities.
