Show steps with solution please!!

Let V be a vector space and W₁, W2 be subspaces of V. Then verify that
W₁ + W₂ = {w₁ +w2 : w₁ € W₁ and w₂ € W₂}
is a subspace of V by verifying the following:
(a) Ổ € W₁ + W₂ (express the zero vector in the form v + w where v € W₁ and u € W₂)
(b) Verify that if v € W₁ + W₂ and c E R is a scalar, then cv € W₁ + W₂.
(c) Verify that if v, ‚ u € W₁ + W₂ then (v + w) ≤ W₁ + W2.
