To analyze the given subspaces, let's start by understanding their properties and finding their bases.For subspace W, we have the following condition:W = { ???? ? ?? | ????? ? 2????? + 2????? + ????? = 0 }A subspace is a subset of a vector space that satisfies certain properties. A vector space is a collection of vectors that can be added together and multiplied by scalars, such as real numbers, and it follows certain axioms or properties.
