## FAQs on RD Sharma Class 8 Solutions Chapter 6 - Algebraic Expressions and Identities (Ex 6.7) Exercise 6.7

1. What is the concept associated with the algebraic expressions and their identities?

The subject and concepts of algebra may seem to be quite new at first for the students preparing for class 8 examinations. Since the concepts are very important to learn, chapter 6 that mostly deals with these identities of variables and algebraic expressions, has been introduced by CBSE in the syllables of class 8. According to the rule of algebra, it primarily deals with the variables and constants. The variable is the representation of a particular value and the algebraic identities signify the laws of equality that will be true in the case of the values represented by the variables.

2. How to solve the equations that involve algebraic identities?

Algebra is a very interesting subject to learn. The laws of algebra help us to assume a numerical value and let us solve the entire equation considering the particular value. To solve the algebraic equations, the students need to memorise certain laws and identities of the algebraic expressions that are considered the standard formulae. Solving algebraic equations is very easy if the students can memorise the formulae properly because these identities are considered to be always true. The students need to solve the algebraic equations while applying these formulae.

3. What is the purpose of learning and memorising algebraic identities?

Algebraic identities are considered foundational concepts. The students can solve complicated equations by applying the laws of algebraic identities. If the students want to pursue their higher academics in mathematics, they need to learn these concepts very well. When they will solve the problems of calculus and derivatives, having a good understanding of these formulae will come in handy. The algebraic identities are considered the standard equations that will be valid in the case of all the values of the algebraic variables. These algebraic identities will help the students to calculate and find out the answers to algebra equations.

4. What is the practical usage of algebraic expressions?

The purpose of inventing these algebraic expressions is to find out the value of something which is unknown and cannot be calculated properly without the help of additional information. The algebraic expressions mostly deal with certain variables and the values of these variables are generally assumed. The constants also play a very important role since the values of these constants will always be fixed under any condition. The students need to apply the formulae of algebraic identities and with the help of the estimated numerical values of the variables, they have to find out the answer.

5. How can the students understand the concept of algebraic expressions and identities easily?

There are various reference books that the students can consult in order to understand the foundational concepts of algebra and to acquire the knowledge of how these algebraic identities are formed. One of the most helpful reference books is RD Sharma Solutions. These books provide the students with detailed knowledge of how these algebraic equations and standard formulae are formed. These books are also important to consult as the questions are solved by the expert subject trainers. The best part is that the books are available on the website of Vedantu for free.
