    Find the formulas

    Find the 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.]

    Not sure how to make matrix's on here but... the question has this presented;

    X 0 0
    Y 0 I

    2x3 matrix

    A Z
    0 0
    B I

    right beside it this one as, 3x2 matrix and finally


    I 0
    0 I

    = 2x2 matrix


    Find the formulas for X, Y, and Z. Note that I represents the identity matrix and 0 represents the zero matrix.

    So err I've never come across a question like this and am kind of confused, could use some tips, thanks.

    Re: Find the formulas

    Got it.

    X = a^-1
    y =-ba^-1
    z = 0
