SUMMARY
The columns of matrix A, given in row reduced echelon form as 1 2 0 0, 0 0 1 0, 0 0 0 1, are linearly dependent. This conclusion arises from the fact that the first two columns are multiples of each other, indicating that there exists a non-trivial solution to the equation A x = 0. The hint provided in the homework emphasizes the importance of understanding the implications of row reduction on linear independence, reinforcing that the only solution to the equation must be the trivial solution for the columns to be independent.
