Solution :
**********************************
We know that ,
( a + b )² - 4xy = ( a - b )²
***********************************
Now ,
( 3x + 5y )² - 60xy
= ( 3x + 5y )² - 4 × 3x × 5y
= ( 3x - 5y )²
= ( 3x - 5y )( 3x - 5y )
••••
**********************************
We know that ,
( a + b )² - 4xy = ( a - b )²

Now ,
( 3x + 5y )² - 60xy
= ( 3x + 5y )² - 4 × 3x × 5y
= ( 3x - 5y )²
= ( 3x - 5y )( 3x - 5y )
