Let A = [1   -5   -3

              -1    3   -1

              4  -17    -4]

We want to determine if the equation Ax=0 has nontrivial solutions.
To do that we row reduce AA.

To do this we add _ times the first row to the second.
We then add _ times the first row to the third.
We then add _ times the new second row to the new third row.
We conclude that

A. The equation has no nontrivial solutions.
B. The equation has nontrivial solutions.
C. We cannot tell if the equation has nontrivial solutions or not. ?
