## FAQs on NCERT Solutions for Class 8 Maths Chapter 8 - Algebraic Expressions and Identities Exercise 8.3

1. What are the properties of polynomial multiplication in class 8 maths chapter 8.3?

It's a little more difficult to multiply polynomials than it is to add and subtract them. To multiply each term in the first polynomial by each term in the second polynomial, we must apply the distributive property. Then we mix similar words. When multiplying binomials, we may also utilise a shortcut known as the FOIL technique.

2. Why are multiplying polynomials important in class 8 math exercise 8.3?

The distributive property allows us to multiply each term of the first polynomial by each term of the second when multiplying polynomials. The goods are then combined and words are combined to streamline the process. Certain particular products have patterns that we may learn and utilise instead of manually multiplying polynomials each time. We'll look at a few different methods for multiplying polynomials.

3. What are algebraic identities in maths class 8 chapter 8 exercise 8.3?

As we studied in exercise 8.3 class 8 solutions, Algebraic identities are algebraic equations that are true for all possible values of the variables in them. Algebraic identities are useful in the factorization of polynomials. On both sides of the equation, there are variables and constants. The left side of the equation equals the right side of the equation in an algebraic identity. For example, for any values of and b, (a+b)2 = a2+2ab+b2 is true.

4. What is the substitution method in exercise 8.3 class 8?

Substitution is the process of replacing variables or characters with numbers or values. The replacement technique involves performing an arithmetic operation by replacing the values for the variables. For eg: x-2=4, x=2.

5. What topics are covered in Class 8 Math 8.3 Exercises?

Maths Class 8 Chapter 8 Exercise 8.3 focuses on using algebraic identities to simplify expressions and solve equations.

6. Why is it important to learn and use algebraic identities of class 8 math exercise 8.3?

Algebraic identities help simplify complex expressions and make calculations more straightforward. They are crucial for solving equations and grasping advanced algebra concepts.

7. What common mistakes should I avoid when using algebraic identities of class 8 ex 8.3?

Common mistakes include confusing the identities, making errors during substitution, and incorrect arithmetic during simplification. Always review your work to avoid these errors and practise more problems from class 8 ex 8.3 to avoid those mistakes in the future.

8. Which is the most important chapter in class 8 maths chapter 8.3?

chapter 8 Comparing Quantities.

chapter 9 Algebraic identities and expressions.

chapter 11 Mensuration.

chapter 12 Exponents and Powers.

chapter 14 Factorisation.

9. Are there any tricks to remembering these identities we studied in class 8 8.3 exercise?

Understanding how each identity is derived and practising them regularly aids in memorization. Mnemonics and visual aids can also be helpful.

10. Which is the most easy chapter in class 8 maths?

The class 8 maths chapter that is the easiest for each student will differ based on their level of interest and comprehension. Nonetheless, in comparison to other chapters, students typically find "Squares and Square Roots" and "Rational Numbers" to be somewhat easier.22 March 2023.
