## FAQs on RD Sharma Class 8 Solutions Chapter 7 - Factorization (Ex 7.1) Exercise 7.1

1. What are the main topics discussed here?

The important topics which have been discussed here are as follows:

What is Factorisation?

Method of Common Factors

Factorization by Regrouping Terms

Factorization Using Identities

Factors of the form (x+a)(x+b)

Division of Algebraic Expressions

Finding the Error

2. What is factorisation?

It is very important for students to understand what factorisation means and to learn how to factorise a given expression.

In order to describe factorisation, we could say:

When we break down a number into smaller numbers that, multiplied together, give you that original number it is called factorization. The smaller numbers are called the factors. It is crucial for students to clearly understand this to solve RD Sharma Class 8 Chapter 7 - Factorization easily.

3. What are the different methods of factorisation?

There are many different methods of finding factors to an expression. The different methods for factorising expressions which have been discussed in RD Sharma Class 8 Solutions Chapter 7 - Factorization is:

Method of Common Factors

Factorization by Regrouping Terms

Factorization Using Identities

Factors of the form (x+a)(x+b)

Students must learn all the methods to solve the questions in RD Sharma Class 8 Chapter 7 - Factorization smoothly.

4. What is an irreducible factor?

While solving questions on RD Sharma Class 8 Chapter 7 - Factorization students must have come across expressions that could not be expressed as a product of other factors. They might have wondered what they are actually called. Some might not have noticed them at all.

Well, there is a specific term for such factors. They are called irreducible factors.

Thus, we can say:

A factor that cannot be expressed as a product of other factors is called an irreducible factor.
