Just a tip those who are going through this
In U+V we can't straight away write the individual basis, because who knows if those two share something common , even if it's not entirely same and in linear combination still that is redundant , that's why all these process.
So we try to reduce that system by RREorm
What I wanted to say is while reducing the answer might carry if we write span{v1, v2, w1, w2} instead of span{v1, w1, v2, w2} then you will see w2 interns of v1, w1, v2.
Edit : this is in fact same mechanism when we try to find coordinate of (x, y) w. R. T. Some basis. We write basis in columns and along side apply the same row operations to the entry of given vector.
