Class 8 Maths Chapter 9 Important Questions

Using identities, evaluate 297 x 303.

297 x 303
= (300 – 3) x (300 + 3)
= 300^2 – 3^2 [ Using (a – b)(a + b) = a^2 – b^2]
= 90000 – 9
= 89991

Using identities, evaluate 78 x 82.

78 x 82
= (80 – 2) x (80 + 2)
= 80^2 – 2^2 [ Using (a – b)(a + b) = a^2 – b^2]
= 6400 – 4
= 6396

In Chapter 9 Algebraic Expression and Identities, we have to learn about the fundamental terms like factors, coefficients, monomial, binomial, trinomial and all other polynomials, like and unlike terms in an algebraic expression, additions and subtractions of expressions taking like terms aside. Multiplications of two or three monomial and the multiplication of a monomial or binomial with a polynomial. Simplification of different polynomials using various identities. The following are the some standard identities:
1. (a – b)² = a² – 2ab + b²
2. (a + b)² = a² + 2ab + b²
3. (a + b)(a – b) = a² – b²

Do you know?

In order to factorize or simplify any algebraic expression, common identities are required. Taking common helps to make the factors of expressions and simplify the factors of two. To understand the algebraic expression in the simplest format, we must remember almost all the identities.
