Question

What is the complete factorization of 4x2 - 9y4?

Answer 1

Answer: D

Explanation:

if you evaluate/simplify the equation you would get 4x^2 - 9y^4.

Answer 2

the answer is c

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

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 )
