Let H, be the subset of V Yuanan Diao that contains all 2 x 2 upper triangular matrices and H2 be the subset of V that contains all 2 x 2 matrices with at most one non-zero entry (that is, every entry in each matrix in H2 is zero with at er most one exception). Choose all statements that are correct. O H 1 is closed under scalar multiplication. O H2 is closed under scalar multiplication. O H1 is closed under matrix addition. O H2 is closed under matrix addition. O H2 is NOT a subspace of V. O H1 is a subspace of V.
