FAQs on RD Sharma Solutions for Class 9 Maths Chapter 6 - Factorization of Polynomials
1. What are the methods of factorization polynomials according to RD Sharma for Class 9 Maths Chapter 6?
Factorization polynomials can be done in a variety of ways depending on the expression. The factorization method is determined by the degree of the polynomial and the number of variables in the equation. The following are the four most common methods for factorization polynomials.
Common Factors Methodology
Method of Grouping
Splitting phrases into factors is a method of factorization.
Algebraic Identities for factorization
It is important to be thorough with the aforementioned terms to be proficient in class 9 mathematics. To learn more, click on the link given above to download the Solutions.
2. How to find the difference between two perfect two squares according to chapter 6 of Class 9 Maths book?
A difference in two perfect squares indicates that there should be two words, one with a negative sign between them and the other with perfect squares in both. After factorization the difference in two perfect squares, the result should have two binomial terms. The difference of two binomial terms is contained in one binomial term, while the total of two binomial terms is contained in the other. We can conclude that, (a² -b²) = (a+b)(a-b).
It is important to grasp this to progress further in the chapter.
3. What is the strategy to find the Greatest Common Factor (GCF), according to chapter 6 of class 9 Maths RD Sharma book?
The primary strategy for factorization polynomials is to find the greatest common factor, which simplifies the problem.
Method to find the Greatest Common Factor:
Completely factor each term in the polynomial.
Create a product in such a way that each factor is shared by all other terms.
Each of these factors has an exponent equal to the smallest exponent found in any of the terms for that factor.
To use this strategy, look at all of the terms and see if any of them have something in common. If there is one, remove it from the polynomial. In addition, we are just utilizing the distributive law in reverse in this example.
4. Write a note on the method of common factors following concepts taught in chapter 6 of class 9 Maths RD Sharma book?
Taking common factors of each of the terms of the provided expression is the simplest way of factoring an algebraic equation. The factors of each and every term of the algebraic expression are written as a first step. To obtain the possible elements, the common factors across the phrases are also taken into account. This is exactly the same as applying the distributive property backwards. With the aid of a demonstration, let us better understand this.
Consider the equation: 3x+9
We have two terms here, 3x and 9. We need to check for a common factor between these two terms. If we observe, 3x is a multiplication of 3 and x, whereas 9 can be written as the multiplication of 3 and 3.
This implies that,
3x+9= 3.x + 3.3 = 3(x+3), according to distributive law
5. How to prepare for Class 9 Maths Chapter 6 - Factorization of Polynomials?
Students should learn the basics of the chapter - factorization of polynomials. Students should have strong fundamentals to do well in this chapter. They should learn the basic concepts of factorization of polynomials like factorization of polynomials, method of common factors, factorization polynomials by grouping, factorization polynomials by splitting terms, factorization polynomials by using algebraic identities, remainder theorem, factor theorem, greatest common factors, long division etc. Students should also try to solve sample papers related to factorization of polynomials. Students should visit the Vedantu app or Vedantu website for free maths class 9 chapter 6 study materials which will make their preparation simple and easy.
