Question

Using identities and factories it : ​

Answer 1

Step-by-Step Explanation :

$1 - 8xy + 16 {x}^{2} {y}^{2} \\ = {(1 )}^{2} - 2(1)(4xy) + {(4xy)}^{2} \\ = {(1 - 4xy)}^{2}$

This is done by using the following identity

(a-b)² = a²-2ab+b²

Hope this will help u....

Nd follow me plz....

Answer 2

Answer:

1-8xy+16x^2 y^2

= 1^2-2*1*4xy+ (4xy)^2

= (1-4xy)^2

=(1-4xy)(1-4xy)
