find the value for k for which the matrix
A=
| 9 -1 11 |
|-6 5 -16 |
| 3 2 k |
has rank= 2
* the spacing on the matrix doesn't seem to want to stay formatted, but it's a 3X3 with row 1= (9, -1, 11), row 2= (-6, 5, -16) and row 3=(3,2, k)
- I tried to solve this using row reduction and then solve for k, but I don't think that's right at all. Can someone please explain this problem to me and the technique for solving it?
