Important Topics covered in Chapter 8 - Algebraic Expressions and Identities

 NCERT solutions for class 8 maths chapter 8 is mainly concerned with the study of polynomial problem solving. Here you will find the important topics covered in chapter 8.

8.1 Addition and Subtraction of Algebraic Expressions - If two algebraic expressions are like terms, we can add or subtract them. For addition or subtraction, we put each expression in different rows, placing each Like Term one above the other.

8.2  Multiplication of Algebraic Expressions: Introduction - This section covers the basics of multiplication of algebraic expressions, the steps associated with multiplication, and the procedures for implementing the results of multiplication.

8.3 Multiplying a Monomial by a Monomial - When a monomial is multiplied by itself, it is called Multiplication of Monomial by a monomial. It consists of only one term, namely a single variable and a single constant. 

For example; x × 3y and 5x × 4y2

In this section, you will learn two types of terms.

 8.3.1 Multiplying two monomials
              8.3.2 Multiplying three or more monomials

8.4 Multiplying a Monomial by a Polynomial - When a monomial is multiplied by a polynomial, it is called a Multiplication of the Monomial by a polynomial.

It is composed of two terms, namely the two constants and the two variables.

For example; 4xy × 5x2y2 and -20x × xyz

In this section, you will learn two types of terms.

            8.4.1 Multiplying a monomial by a binomial
            8.4.2 Multiplying a monomial by a trinomial

8.5 Multiplying a Polynomial by a Polynomial - When a polynomial is multiplied by a polynomial, it is referred to as the multiplying a polynomial by a polynomial.

It's a set of things that have two or more terms, like a group of constants and variables.

For example: (3a + 4b) × (2a+3b) and (x-4) × (2x+3)

In this section, you will learn two types of terms.

            8.5.1 Multiplying a binomial by a binomial
            8.5.2 Multiplying a binomial by a trinomial

Frequently Asked Questions

Question 1. What are Algebraic Expressions in NCERT solutions for class 8 maths chapter 8 ?

Answer 1. In NCERT solution for class 8 maths an algebraic expression is an equation or a combination of a variable, a number and an algebraic operation (addition, subtraction, multiplication etc.). An Algebra is a set of terms, such as a variable, coefficients, or a constant. For example 2x + 5y - 3. Here, 2 and 5 are coefficients, x and y are variables, and ‘3’ is a constant. Algebraic expressions can be divided into three types: monomials, binomials, and trinomials.
