Let A be an m×n matrix. If these exist two distinct vectors v1 and v2 such that Av1=Av2 then there exists a non-zero vector, v, such as that Av= 0. Explain why this must be true. I'm a bit confused about this question, my first thought is that if the vectors always equal each other when multiplied by A, and the vectors are distinct (Assuming non-zero as well due to how the question is worded) then it must be that A is the reason they always equal and that A causes both sides to equal zero.

Question:
Let A be an m×n matrix. If these exist two distinct vectors v1 and v2 such that Av1=Av2 then there exists a non-zero vector, v, such as that Av= 0. Explain why this must be true.

I'm a bit confused about this question, my first thought is that if the vectors always equal each other when multiplied by A, and the vectors are distinct (Assuming non-zero as well due to how the question is worded) then it must be that A is the reason they always equal and that A causes both sides to equal zero. However I feel like I've gone in the wrong direction when thinking about this problem, any help would be appreciated!
