1. Let X be the set of vectors in R' which are orthogonal to both 2 and Express X in two ways: first, by finding a matrix A for which X Null(A), then by finding a matrix B for which X-Col(B). There are many different possible choices for A and B, but there is only one possible value for the rank of each. Explain what the rank of A must equal, and what the rank of B must equal, and why,
