NCERT Solutions Class 8 Maths Chapter 9 Algebraic Expressions and Identities

 

Introduction :

In this chapter we will learn about like and unlike term , factors , coefficient , addition and subtraction , multiplication of algebraic expressions. Monomials , binomials , trinomials , polynomials and multiplying three or more monomials multiplying three or more polynomial multiplying three or more binomials multiplying three or more trinomials and applying identities = ( a + b )2 = a2 + 2ab + b2 and ( a - b )2 = a2 - 2ab + b2 and ( x + a ) ( x + b ) = x2 + ( a + b ) x + ab and ( a - b ) ( a + b ) = a2 - b2 and product means ( multiply ) .

NCERT Class 8 Maths Algebraic Expressions and Identities Exercise 9.1

In this Exercise-9.1 we will learn about expressions, four terms Monomial, Binomial, trinomial, Polynomial and terms, factors and coefficients of addition and subtraction of algebraic expressions find out Monomial, Binomial, trinomial, Polynomial the numerical factor of a term is called its numerical coefficient or simply coefficient.

NCERT Class 8 Maths Algebraic Expressions and Identities Exercise 9.2

In this Exercise-9.2 we will learn about multiplication of algebraic expression. Multiplying a monomials by a monomials and multiply two monomials and multiplying three or more monomials find out factor of monomials. [ using identity = volume of rectangle = Length × Breadth × Height ] only on using formula and multiply do in this exercise .

NCERT Class 8 Maths Algebraic Expressions and Identities Exercise 9.3

In this Exercise-9.3 we will learn about multiplication of algebraic expressions. multiplying a monomials by a polynomial and multiplying a monomials by a binomial and multiplying a monomials by a trinomial and multiply or add and subtract then do this exercise.

NCERT Class 8 Maths Algebraic Expressions and Identities Exercise 9.4

In this Exercise-9.4 we will learn about multiplication of algebraic expressions. multiplying a polynomials by a polynomial and multiplying a binomials by a binomials and multiplying a binomials by a trinomials. Only on multiply do in this exercise. Most important thing bracket multiply bracket.

NCERT Class 8 Maths Algebraic Expressions and Identities Exercise 9.5

In this Exercise-9.5 we will learn about multiplication of algebraic expressions. [ using identity = ( a + b )2 = a2 + 2ab + b2 and ( a - b )2 = a2 - 2ab + b2 and ( x + a ) ( x + b ) = x2 + ( a + b ) x + ab and ( a - b ) ( a + b ) = a2 - b2 you learn identity before then do this exercise. In all question put on identity.
