Find formulas for X, Y, and Z in terms of A and B. It may be necessary to make assumptions about the size of a matrix in order to produce a formula. [Hint: Compute the product on the left, and set it equal to the right side.] A Z X 0 0 0 0 YOI B . . . . . Find the formulas for X, Y, and Z. Note that I represents the identity matrix and 0 represents the zero matrix. X = A Y= A Z = 0
