Ways to tell them apart:
Extend can imply length, affecting how far something reaches, while expand implies increased size in volume or area.
Extend often involves something being made longer, like extending a deadline or extending a hand in greeting.
Expand is about growing or spreading out, like a balloon inflating or a company expanding into new markets.
Remember that extend is more linear, as in extending a path, whereas expand is more about an increase in area or space.
Extend typically involves an addition to something already existing, whereas expand can involve creation of new space or volume.
