Answer 1

Hello :D ✨

Step-by-step explanation:

$(ab - bd {)}^{2} - (bc + ad {)}^{2}$

$(ac - bd - (bc + ad)) \times (ac - bd + (bc + ad))$

$= (ca - bd - (bc + ad)) \times (ac - bd + (bc + ad))$

$= (ac - bd - bc - a) \times (ca - bd + (bc + ad))$

$= (ca - bd - bc - ad ) \times (ac - bd + (bc + ad))$

$= (ca - bd - bc - ad) \times (ca - bd + bc + ad)$

HOPE IT HELPS ❤️
