Find The Products Of The Following Using The Identity A B 2 Let's go through each of the expressions and find their products using standard algebraic identities. i'll explain each one step by step. this expression follows the identity (a−b)2=a2−2ab b2. therefore, (a−b)2=a2−2ab b2. use the identity (a b)2=a2 2ab b2. here, a=2a and b=3b. (2a 3b)2=(2a)2 2(2a)(3b) (3b)2=4a2 12ab 9b2. Ex 2.4, 1 use suitable identities to find the following products: (iv) (y2 3 2 ) (y2 – 3 2 ) (y2 3 2 ) (y2 – 3 2) by using the identity (a b) (a – b) = a2 – b2 , where a = y2 , b = 3 2 = (y2)2 – (3 2)^2 = y4 – 9 4. We will use the given algebraic identities to find the products and evaluate the expressions step by step. using the identity (a b)2 =a2 2ab b2, we find the product for (3x 9)^2: (3x 9)2 =(3x)2 2(3x)(9) (9)2 = 9x2 54x 81. using the identity (a b)2 =a2 2ab b2, we find the product for (2x1 x)2: (2x1 x)2 =(2x1)2 2(2x1)(x) x2 = 4x21 1 x2. Using identity a2 2ab b2 (3x 9)2= 3x^2 2(3x)(9) 9^2 = 9x^2 54x 81. using the identity again 9x^2 54x 81 = 3x^2 9^2 2(3x)(9) = (3x 9) (3x 9).

Using identity a2 2ab b2 (3x 9)2= 3x^2 2(3x)(9) 9^2 = 9x^2 54x 81. using the identity again 9x^2 54x 81 = 3x^2 9^2 2(3x)(9) = (3x 9) (3x 9).
