Linear Algebra Question: Solving a Matrix with k=-2 and Transposition

[transgalactic]

i got this matrix
1 1 k
0 1-k k-1
0 0 (k-1)(k+2)

for k=-2
1 1 -2
0 -1 -3
0 0 0


the k matrix is row reduced
so after i put k=-2 and transposed it.
i get no all 0 lines
so i need to do row reduction again??

What's the actual question?

 

[transgalactic]

what is the general way of finding Im

 

[Mark44]

What does that mean--"finding Im"?

Going back to your first post, you said you "put k=-2 and transposed it." What does "it" refer to? The matrix? Or do you mean that you interchanged two rows?
