Question

 i. Find a spanning set for W

ii. Trim that spanning set in (i) to form a basis of W. Describe dim W. 

iii. Extend that basis in (ii) to a basis of V. 

iv. Based on your answer in (iii), find a subspace W' of V such that W W' = V. 

1. Consider
x +y+ z+ 2w + v
3x + 4y + 3z + 3w + 5v
W =
— 2я — Зу — w - 6у
|x, y, z, w E R
2ж + 4у + 22—— 2w + 6v
3x + 2y + 3z + 9w + v
which is a subspace of V = R° (DO NOT SHOW THIS
ANYMORE).
