What identity can be used to rewrite the expression 4x^2-9

[(2x)² - 3²] = (2x-3) (2x+3)

Step-by-step explanation:

The given expression is ( 4x² - 9)

We have to tell the identity to factorize the given expression.

We can rewrite the expression as [ (2x)² - 3² ]

To factor if we will use the identity

[a² - b² = (a-b) (a+b) ]

so expression will become

[(2x)² - 3²] = (2x-3) (2x+3)
