Answer 2

Answer:

↓

Step-by-step explanation:

4 x 2 − 9

Rewrite  

4 x 2  as  ( 2 x ) 2 . ( 2 x) 2 − 9

Rewrite  

9 as  3 2 . ( 2 x ) 2 − 3 2

Since both terms are perfect squares, factor using the difference of squares formula,  

a 2 − b 2 = (a + b ) ( a − b )

where  

a = 2 x

and  

b = 3 . ( 2 x + 3 ) ( 2 x − 3 )
