Hey everyone I need to make this matrix as products of elementary matrices I cannot seem to get the answer, I've done it multiple times and this is what I get for the answer: Can someone please help figure out what I am doing wrong. Thanks

I'm sorry, but what does it mean to make it the product of elementary matrices? It looks pretty elementary to me, unless that's a particular term.

This much is correct: Now what you want is to add the first row to the second row, so premultiply by , and finish by premultiplying with row multiplications.
