    Finding a basis of a space

    So my second try is correct? Better to let w1, w2, w3, w4, w5 instead of x...?

    Finding a basis of a space

    Let u = [1, 2, 3, -1, 2]T, v = [2, 4, 7, 2, -1]T in ℝ5. Find a basis of a space W such that w ⊥ u and w ⊥ v for all w ∈ W. I think the question is quite easy. Given this vector w in the space W is orthogonal to both u and v. I can only think of w being a zero vector. But would this be too...
