could you please help me with 5 and 6 and can you please provide explanations

2. Below is a list V₂ of vector spaces over R. You are given subsets US Vi. Decide which
of these are subspaces. Justify your answers by giving a proof or a counter-example in each
case.
(1) V₁ = R¹ and U₁ = { (a0, a₁, A2, a3) € R¹ | Σ²_o a; = 0}.
i=0
(2) V₂ = R³ and U₂ = { (a, b, c) € R³ | ab = c}.
(3) V3 R³ and U3 =
{(a + b, b, a + b): a, b ≤ R}.
(4) V₁ = R³ and U₁ = {(a, b, c) € R³: a+b+c = 0 and b + c = 0}.
(5) V5 = R³ and U5 = {(a, b, c) € R³ : a =0 or b=0 or c = 0}.
(6) V6 R[x] is the vector space of polynomials with real coefficients (this was example
3 in the lecture). U6 = {p E R[x] : p(1)=0}.
