This is an introductory lesson on factorisation of algebraic expressions and explores some techniques involved
Introduction to CBSE Class 8 Mathematics Chapter "Factorisation"
“Factorisation” is a key chapter in the CBSE Class 8 Mathematics syllabus that delves into breaking down algebraic expressions into their simplest form. This chapter introduces students to the concept of factors of natural numbers, which are then extended to polynomial expressions. It begins with the factorisation of common terms and advances to techniques such as regrouping terms, splitting the middle term, and using identities to simplify and solve quadratic and cubic polynomial expressions.
The chapter aims to strengthen students’ understanding of how factorisation is applied to simplify algebraic expressions and solve equations efficiently. By mastering factorisation, students can solve a variety of problems, including those involving finding values of algebraic expressions for specific values of variables. Factorisation also plays a significant role in finding the LCM and GCD of polynomials, thereby linking arithmetic to algebra.
