Answer 1

Hello Friend,

Here,

4n² - 9y² - 2n - 3y
= (2n)² - (3y)² - (2n + 3y)

[Now, a² - b² = (a+b)(a-b) ]

= (2n+3y)(2n-3y) - (2n+3y)
= (2n+3y)(2n-3y-1)

[Here, we take (2n+3y) as common ]

Hope it helps.

Answer 2

see
=4x^2- 9y^2-2x-3y
={(2x)^2-(3y)^2}-1(2x+3y)
=(2x+3y)(2x-3y)-1(2x+3y)
=(2x+3y)(2x-3y-1) (ans.)
