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.
