Hi,
I am not sure if I am answering this correctly. I have shown that scalars a,b,c,d are not linear independent..but what does that mean for span??Linear indep isnt neccessary for span right?..
please check this attachmenthas my answer.
I was sure I knew what span was.I would appreciate feedback.thankyou.

Your matrix should have four rows instead of 3 (and you should get a row of zeroes for one row after row reduction).
