# NCERT Solutions Class 8 Maths Chapter 14 Factorisation

## Introduction :

In this chapter we will learn about Factorisation. We can express algebraic expressions as products of their factor. this is what we will learn to do in this chapter. **What is Factorisation? When we Factorise an algebraic expression, we write it as a product of factors. These factors may be numbers, algebraic variable or algebraic expressions. **A number written as a product of prime factor is said to be in the prime factor form.

In this Exercise-14.2 we will learn about Factorisation. Factorisation using identities. Factors of the form **( x + a ) ( x + b ). **In general, for factorsing an algebraic expression of the type x^{2} + px + q, we find two factors a and b of q ( i.e., the constant term ).

In this Exercise-14.4 we will learn about Factorisation. Can you find the error. We know that in the case of numbers, division is the inverse of multiplication. This idea is applicable also to the division of algebraic expressions. Bracket means multiply .
