## FAQs on RS Aggarwal Solutions Class 8 Chapter-7 Factorisation (Ex 7C) Exercise 7.3

1. What are Factors and Factorization in class 8 chapter-7?

Factors are the numbers or algebraic expressions which can be written as a product of other numbers or algebraic expressions. Example: 30=10*3, here 10 and 3 are factors of 30. But there can be many other factors of 30 also.

Likewise in an algebraic expression like 3ab, 3ab=3*a*b. In this 3, a, and b all are the factors of 3ab and it is an irreducible factor as it cannot be factored further. In such types of questions, it is easy to find factors but in other questions where the product is not given like a2+b+3 then we need a certain method to find its factors.

2. What is factorization by using common terms and by regrouping the terms in class 8?

When we talk about factorization using common terms, in this, we take common factors to change the algebraic expression into product format, and then you can express it as a product of irreducible factors. Example factors of 3a+9 will be 3a=3*a and 9=3*3

Factorization Using Common Terms: Here, we take common factors so as to change the algebraic expression into product form and then express it as a product of irreducible factors.

Factors by Regrouping The Terms: in order to find the factors sometimes we need to regroup the terms.

3. What are the important formulas of class8 chapter 7- factorization?

There are tricky questions where we need to apply formulas to find the factors of algebraic expression. The important formulas are :

1. (a+b)2 = a2 + 2ab + b2

2. (a-b)2 = a2 – 2ab + b2

3. (a + b) (a – b) = a2b2

You have to learn these formulas in order to solve difficult questions in exams. RS Aggarwal solutions class 8 chapter 7 - factorization by Vedantu, provides multiple questions that you can practice and get a good result. You should practice 1 exercise each day to prepare for exams

4. What does RS Aggarwal Solutions Class 8 Chapter-7 Factorisation (Ex 7C) Exercise 7.3 include?
