1 2 1. Consider the matrix A = 1 0 . Since A is not square, it is not invertible. However, for some 0 1 non-square matrices, we can get \"one-sided inverses". (a) Find a matrix B such that BA 2 I (where I is the appropriately sized identity matrix), or explain why no such matrix exists. (b) Find a matrix C such that AC : I (where I is the appropriately sized identity matrix), or explain why no such matrix exists
