Important Topics covered in Chapter 12  Factorisation
NCERT solutions for class 8 maths chapter 12 covers all the main topics of factorization. Here, we will discuss all the topics included in chapter 12.
12.1 Introduction 
12.1.1 Factors of natural numbers 12.1.2 Factors of algebraic expressions 
12.2 What is Factorisation ? 
12.2.1 Method of common factors 12.2.2 Factorisation by regrouping terms 12.2.3 Factorisation using identities 12.2.4 Factors of the form (x + a) (x + b) 
12.3 Division of Algebraic Expressions 
12.3.1 Division of a monomial by another monomial 12.3.2 Division of a polynomial by a monomial 
12.4 Division of Algebraic Expressions Continued (Polynomial ÷ Polynomial) 
12.1 Introduction  In this section, you will learn about the factorisation of natural numbers and algebraic expressions.
12.1.1 Factors of natural numbers
12.1.2 Factors of algebraic expressions
You have learned about natural numbers in your previous classes. Now, you are going to learn how to factorize a natural number into prime factors. For example, if we have a natural number 45, then its prime factor is 3 * 3 * 5.
In your previous classes, you have already learned about Algebraic Expressions. Now, you are going to learn how to factorise an Algebraic expression into the prime factor. For example, if we have an algebraic expression 3xy, its prime factor is 3 * x * y
12.2 What is Factorisation ?  When we factorise an algebraic expression, This makes it easy to understand the expression as a product of its factors. These factors are natural numbers, Algebraic variables or Algebraic expressions.
For example, 2xy, 5x^3y, and 5x(y+2) are factorised forms.
In the following examples, the expression (2x + 4) and the expression (5x^2 + 9) are not in factorised form. To transform the expression in the form of a factor, we are going to use the following methods:
12.2.1 Method of common factors
12.2.2 Factorisation by regrouping terms
Regrouping  We will rearrange the algebraic expression (Ex. 3xy+2+3+2ab), which will allow us to form the group (ex. 3xy+3+2ab+2), leading to factorisation.
12.2.3 Factorisation using identities
12.2.4 Factors of the form (x + a) (x + b)
The abovementioned methods will explain how to factorize any natural numbers or algebraic expressions.
12.3 Division of Algebraic Expressions  Division, as mentioned in previous chapters, is the inverse operation of multiplication. For example, 5*6=30 gives 30÷5=6 or 30÷6=5.
12.3.1 Division of a monomial by another monomial Here, you will learn to divide a monomial by another monomial.
For example, To divide 6x^2 to 2x,
Step1  factorise the monomial 2*3*x*x and 2*x
Step2  cancel the matched factor by their denominator
(2*3*x*x ÷ 2*x) = 3*x
12.3.2 Division of a polynomial by a monomial  Here, you will learn to divide a polynomial by a monomial.
For example, divide 6x^2(2x + y) by 2x
Step1: factorise the polynomial and monomial 2*3*x*x*(2*x + y) and 2*x
Step2: cancel the matched factor by their denominator
[2*3*x*x*(2*x + y) ÷ 2*x] = 3*x(2x + y)
12.4 Division of Algebraic Expressions Continued (Polynomial ÷ Polynomial)  This section will teach you to divide the polynomial by the polynomial.
For example, To divide (7y^2 + 14x) to (y + 2)
Step1: factorise the polynomial and polynomial
7*y*y + 7*2*y and (y + 2)
7*y(y +2) and (y + 2)
Step2: cancel the matched factor by their denominator
[7*y(y +2) ÷ (y + 2)] = 7*y
