Solution :

******************************************

We know the algebraic identity :

a² - b² = ( a + b )( a - b )

****************************************

Now ,

4x² - y²/9

= ( 2x )² - ( y/3 )²

= ( 2x + y/3 )( 2x - y/3 )

Yo!
Your Answer.

4x² - y² / 9

2²x² - y²/3²

(2x)² - (y/3)²

Using a² - b² = (a-b)(a+b)

(2x + y/3) (2x - y/3)
