## Solutions to RS Aggarwal for Class 8

## FAQs on RS Aggarwal Class 8 Mathematics Solutions for Chapter-7 Factorisation

**1. What do you mean by Regrouping in Factorisation?**

When talking factoring algebraic expressions, there is always a chance that there may not be any common variables in that equation, per se. Maybe one or two common variables out of four or six, but not more. In such cases, we must group these common variables and leave the ones which don’t fit and try to find commonalities in all of them. While doing this, we can find common factors and put them in appropriate brackets, so that the factors of an algebraic expression can be thus found. This process is called regrouping and is important in terms of factorising algebraic expressions.

**2. What are the different ways of factorising numbers and algebraic expressions?**

To factorise numbers, we may use the simple common factor method to find the factors of a number. This method can even be used with simple algebraic expressions which have all of the common variables. However, there are two other methods which we may use to factorise numbers and expressions, which are slightly more complex than the common factor method but are required when considering different variables. These methods are the regrouping method (where we put common factors in separate groups and bring them as factors separately) and the identities method, where we use the simple algebraic identities to find out the factors of an expression.

**3. What are some of the concepts included in the RS Aggarwal Class 8 Mathematics Solutions for Chapter-7 Factorisation?**
