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)
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)
