Consider subsets W of a vector space V: (a) V = R³, W = {[x₁, x2, x3] | − 2x1 − 2x2 + x3 = 0}; (b) V = R³, W = {[ab, 3b+ 2a, a - b] | a, b = R}; (c) V = R¹, W = {[X1, X2, X3, X4] | − 2x1 − 2x2 + x3 + x4 = 5}. In each case determine if the given subset W of a vector space V is a subspace. In cases when W is a subspace of V, find a basis and the dimension of W. Justify every step of your answer.
