Homework Statement
Give a matrix B so that the subspace W defined in part b (W = (1,1,0,-2),(1,-1,1,6),(0,1,1,4)) can be written as
W = N(B) where N(B) is the null space of B
Homework Equations
none that I know of, other than N(A) = {vectors x | Ax = 0}
The Attempt at a Solution
I have no clue where to begin. I did not know it was possible to reverse engineer 3 which represent a null space to find the original matrix. Any idea on how to start this problem? I'm utterly lost.
