What is the complete factorization of 4x2 - 9y4?
Liono4ka [1.6K]

Answer:

<em>the answer is c</em>

( 2 x + 3 y ) ( 2 x − 3 y ) is the factored form of the expression

Step-by-step explanation:

  • 4 x 2 − 9 y 2 can be also written as ( 2 x ) 2 − ( 3 y ) 2
  • Now, as per identity: a 2 − b 2 = ( a + b ) ( a − b )
  • So , in case of our expression a = 2 x , b = 3 y ( 2 x ) 2 − ( 3 y ) 2 = ( 2 x + 3 y ) ( 2 x − 3 y )
