Hello everyone, i'm finishing up some matrices review and im' confused on this question i have the matrix:(adsbygoogle = window.adsbygoogle || []).push({});

-1 -3 -1 2

5 13 3 -8

3 10 9 -8

1 4 7 -4

I row reduced got this:

1 0 0 3/5

0 1 0 -4/5

0 0 1 -1/5

0 0 0 0

So you can see that this isn't a basis due to column 5 not being 0 0 0 1, but what does this mean the questions says:

If they are linearly dependent, determine a non-trivial linear relation - (a non-trivial relation is three numbers which are not all three zero.) Otherwise, if the vectors are linearly independent, enter 0's for the coefficients, since that relationship always holds.

?A + ?B + ?C + ?D = 0.

I tried 1 1 1 3/5

1 1 1 0, i tried actually 14 times, all of them are wrong hah, any help?>
