SUMMARY
The discussion focuses on identifying a linearly independent subset F of the set E={x^3, x^3-x^2, x^3+x^2, x^3-1} that spans the subspace U of P3(ℝ). The solution involves setting up a linear combination of the vectors in E and solving the resulting equations to find relationships among the coefficients. It is established that the vectors can be represented in a matrix form, which can then be row-reduced to identify pivotal columns, indicating the linearly independent vectors.
