Question

By using suitable identity find the product of i.(2x+3)(2x-3).ii.(3x+1)^3.iii.(97)^3.iv.9.6×10.4​

Answer 1

Answer:

i. 4x^2 - 9

ii. 9x^2 + 6x + 1

Step-by-step explanation:

i.

(2x+3)(2x-3) (a+b)(a-b) = a^2-b^2

2x^2 - 3^2

4x^2 - 9

ii.

(3x+1)^3 (a+b) = a^2+b^2+2ab

(3x)^2 + (1)^2 + 2(3x)(1)

9x^2 + 1 + 6x

9x^2 + 6x + 1

This is it

Hope it helps..........
