Homework Statement
Construct a matrix whose nullspace consists of all combinations of (2,2,1,0) and (3,1,0,1).
Apparently, the answer is:

Homework Equations
Ax = b (where x and b are vectors and A is a matrix) (in this case, b = 0)
The Attempt at a Solution
As I understand it, I am supposed to find a matrix that, when multiplied with any vector in a certain vector space, I get b = 0. Assuming that I am right theoretically, I need help to continue from here in practice.
Any help in figuring out how to do this problem would be greatly appreciated!
