5 ( 2x + 1 )( 3x + 5 ) - ( 2x + 1 )
=( 2x - 1 ) ( 3x + 5 )( 5 ) - 1 )
= ( 2x - 1 )( 15x + 25 - 1 )
= ( 2x - 1 )( 15x + 24 )
= ( 2x - 1 )( 3 )( 5x + 8 )
= 3 ( 2x - 1 )( 5x + 8 )
=( 2x - 1 ) ( 3x + 5 )( 5 ) - 1 )
= ( 2x - 1 )( 15x + 25 - 1 )
= ( 2x - 1 )( 15x + 24 )
= ( 2x - 1 )( 3 )( 5x + 8 )
= 3 ( 2x - 1 )( 5x + 8 )
