Yes, you nailed it. @Yo0. A counterexample would be sufficient proof to show that this is not a subspace. Both of these vectors would be in S S but their sum will not be since −(1)(1) + (0)(0) ≠ 0 − ( 1) ( 1) + ( 0) ( 0) ≠ 0. Since the addition property is violated, S S is not a subspace.Show the Subset of the Vector Space of Polynomials is a Subspace and Find its Basis; Find a Basis for the Subspace spanned by Five Vectors; Prove a Group is Abelian if $(ab)^2=a^2b^2$ Find a Basis and the Dimension of the Subspace of the 4-Dimensional Vector SpaceMar 2, 2017 · We will prove that T T is a subspace of V V.
