How to calculate basis for two subspaces stack overflow?

I have the bases of two subspaces, Y1 and Y2, and I want to calculate the basis of Y1+Y2.
I put the vectors of the two bases in a matrix and performed row operations until the matrix is in row reduced form. Since the matrix is in this form, the vectors represented by the non-zero lines of the resulting matrix are linearly independent and therefore they are a basis of Y1+Y2.
