Answer:
No, H is not a subspace of the vector space V.
Step-by-step explanation:
A matrix is a rectangular array in which elements are arranged in rows and columns.
A matrix in which number of columns is equal to number of rows is known as a square matrix.
Let H denote set of all 2×2 idempotent matrices.
H is a subspace of a vector space V if for and .
Let
As , A is idempotent.
So,
So, A+A is not idempotent and hence, does not belong to H.
So, H is not a subspace of the vector space V.
