Do you know what the span is? If you don't, you need to read on a bit more before you can answer this question.
If you do, then you can definitely solve the question; the question is asking for a matrix such that . Hint : fill up the matrix with variables, and obtain equations which need to be satisfied by the coefficients of the matrix for the statement to hold. You should be able not only to obtain one such matrix M, but a whole parametrized family of them.
