Solutions for Class 9 Maths Chapter 4 Algebraic Identities Exercise 4.1

Important Definition RD Sharma Chapter 4 Class 9 Maths Exercise 4.1 Solutions

RD Sharma Chapter 4 Class 9 Maths Exercise 4.1 Solutions is based on the following formulas- Look down for some examples based on the formulas of algebraic identities mentioned above-

Ques)- (3p – 1/p)²

Solution- (3p – 1/p)²

= Algebraic Identity- (a-b)² = a² – 2ab + b²

= (3p – 1/p)² = (3p)² – (2 x 3p x 1/p) + (1/p)²

= 9p² – 6 + 1/p²

Ques)- (3x + y) (3x – y)

Solution- (3x + y) (3x – y)

= Algebric Identity- (a + b) (a – b) = a² – b²

= (3x + y) (3x – y) = 3x² – y²

= 3x² – y²

Ques)- 175 x 175 +2 x 175 x 25 + 25 x 25

Solution- 175 x 175 +2 x 175 x 25 + 25 x 25

= Algebraic Identity- a² + 2ab + b² = (a+b)²

= (175)² + 2 (175) (25) + (25)²

= (175 + 25)²

= (200)²

= 40000

3. The answers to the questions are presented organized stepwise in an easy way.

Ques 1- How many algebraic identities are there?

Ans)- There are majorly four algebraic identities. The algebraic identities are used by using basic formulas mentioned below- Ques 2- What is algebraic identity?

Ans)- An algebraic identity is an identity that exists for any values of its variables.

Ques 3- Are all identity equations?

Ans)- An equation satisfied for all variable values determining the expressions is termed as an identity. So, the identity is a unique case of an equation.

In other words, all identities can be equations, but not all equations will be identities.
