Question

which identify Can be used to factories 4x²-9y²​

Answer 1

Answer:

The identity to be used is:

(a²-b²)=(a-b)(a+b)

4x²-9y²=(2x)²-(3y)²=(2x+3y)(2x-3y)

Answer 2

Answer:

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

Step-by-step explanation:

4x² - 9y²

= ( 2x )² - ( 3y )²

a² - b² = ( a + b ) ( a - b ) { Identify / formula }

Here,

a = 2x

b = 3y

4x² - 9y²

= ( 2x )² - ( 3y )²

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

Hence, factorised.
