Question

use a suitable identity to get each of the following product:
(1) (4x - 8) *(4x + 8)​

Answer 1

$(4x - 8)(4x + 8) \\ = {(4x)}^{2} - {8}^{2} \\ = 16 {x}^{2} - 64(ans)$

identity used (a+b)(a-b) = (a^2 - b^2)

Answer 2

Answer:

16x^2-64

Step-by-step explanation:

(4x-8)×(4x+8)

(4x)^2-(8)^2

16x^2-64

Identity used - a^2-b^2=(a+b)(a-b)
