FAQs on RD Sharma Class 8 Solutions Chapter 6 - Algebraic Expressions and Identities (Ex 6.6) Exercise 6.6
1. Write down steps to add two Algebraic Equations as mentioned in Chapter 6 - Algebraic Expressions and Identities.
The following steps are included in the Addition of two or more algebraic equations:
Step 1:- Group all the like elements together, Like elements are co-efficient consisting of the same variable.
Step 2:- Now, all the grouped elements (co-efficient) under the same variable are added and then written as a single coefficient term with the respective variable of the group.
Step 3:- Similarly for other variables, the process will remain the same.
Step 4:- For constant, just add them, no need to do anything else.
2. What are the Monomials, Binomials, and Polynomials as mentioned in RD Sharma Class 8 Chapter 6?
Monomials: A monomial only contains one term at most, this term is the product of non-negative powers of variables. Monomials don’t have any variable as
their denominator. For example:- 3x, 14, - 4x2
Binomials: A binomial is the combination (Addition or Subtraction) of two monomials. And therefore have two, unlike terms. For example:- 4x + 1, y - 2y2
Polynomial: All the combinations of two or more monomials are called Polynomials. Binomials and trinomials can be used as examples. For example:- 3x + 1 - 9x2 or y3 - 4y2 + 2y + 1.
3. Where can I access the solutions of other exercises in Chapter 6?
Chapter 6 - Algebraic Expressions and Identities consists of 7 exercises in total, students can access the solutions to all the questions in those seven exercises from the links given below to the relevant pages on the web platform of Vedantu.
Given below are the links to the solutions of all four exercise questions of Chapter 6 of RD Sharma of Class 8 -
Other than the exercise questions of the RD Sharma book, Vednaut also provides the solutions to the previous year's questions paper and Sample papers.
4. Write down steps to multiply two Algebraic Equations as mentioned in Chapter 6 - Algebraic Expressions and Identities?
The following steps are included in the multiplication of two or more algebraic equations.
Step 1:- In the first step, we take each and every term of the first and multiply them by each and every term of the second expression.
Step 2:- While multiplying the term with the same variable, we will add their powers by the “product rule”.
Step 3:- If the variables are different then just write as the product along with the other variable.
Step 4:- While multiplying coefficients, remember like-sign terms will provide positive results and unlike sign terms, will give negative results.
Step 5:- Resulting terms should be separated by their respective signs.
