Transcribed Image Text:(1) A subset W in a vector space V in R³ is given by
w = { u = ( ) [(x + y)² + z² = 0}.
In R³, (x + y)² + z² = 0 is identical to x + y = 0 and z = 0, and accordingly,
W is an intersection of subsets W₁ and W₂:
W = W₁nW₂;
1
² = { u = (²) |x + y = 0 } ;
W₁ =

Prove that both W₁ and W₂ are subspaces of V. If so, W is also a subspace
of V.
