Chapter 7- Factorisation

In the previous classes, you have learned how to find the factor of a natural number, the element of an algebraic expression. In this chapter, you will learn what are factors, what is factorization, how to find common factors, factorization by regrouping terms, factorization by using identities, how factoring can be used to divide algebraic expressions, and how to find factors of a perfect square. This chapter is divided into 5 exercises (Exercise- 7A, 7B, 7C, 7D, 7E) and consists of 157 questions overall. 

  • Exercise 7A consists of 28 questions and is based on finding factors of algebraic expressions using common factors.

  • Exercise 7B consists of 28 questions and is based on finding factors of the given algebraic expressions using identities. 

  • Exercise 7C consists of 19 questions and is based on finding the factors of given algebraic expressions using identities. It is the continuity of the previous exercise.

  • Exercise 7D consists of 42 questions and is based on the concept of factorization by regrouping the terms of an algebraic expression. 

  • Exercise 7E consists of 20 questions, it is a miscellaneous exercise with all the concepts discussed in the previous chapters.

To learn these concepts in an easy manner with in-depth understanding, Vedantu provides RS Aggarwal Solution for Class 8 Chapter 7- Factorisation, (Ex- 7D) Exercise 7.4- PDF for free. 

FAQs on RS Aggarwal Solutions Class 8 Chapter-7 Factorisation (Ex 7D) Exercise 7.4 - Free PDF

1. What are the rules to be followed to find the errors according to RS Aggarwal Solutions Class 8 Chapter-7 Factorisation (Ex 7D) Exercise 7?

Coefficient 1 of a term is not usually written. But while adding like terms, it should include them in the sum.

  • When substituting a negative value, we should make use of brackets.

  • When multiplying an expression enclosed within brackets by a constant or a variable outside, we should multiply each term of the expression with that constant or variable.

  • When squaring a polynomial, we should square the numerical coefficient and each factor.

  • When dividing a polynomial by a monomial, we should divide each term of the polynomial in the numerator by the monomial in the denominator.
