## 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.

^{2}+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

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 :

(a+b)

^{2}= a^{2}+ 2ab + b^{2}(a-b)

^{2}= a^{2}– 2ab + b^{2}(a + b) (a – b) = a

^{2}– b^{2}

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
