(3d-5)(4-d)
= 3d(4-d)-5(4-d)
= 12d-3d²-20+5d
= -3d²+12d+5d-20
= -3d²+17d-20
= 3d(4-d)-5(4-d)
= 12d-3d²-20+5d
= -3d²+12d+5d-20
= -3d²+17d-20

Hi ,
( 3d - 5 )( 4 - d )
= 3d( 4 - d ) - 5( 4 - d )
= 3d × 4 - 3d × d - 5 × 4 - 5 ( - d )
= 12d - 3d² - 20 + 5d
= 17d - 3d² - 20
= -3d² + 17d - 20
I hope this helps you.
