I'm pleading with mathematicians here, pls help me solve this linear algebra:
A square matrix A is said to be idempotent if A2 = A. Let A be an idempotent matrix.

(a) Show that I − A is also idempotent.

(b) Show that if A is invertible, then A = I.

(c) Show that the only possible eigenvalues of A are 0 and 1. (Hint: Suppose x is an eigenvector with associated eigenvalue λ and then multiply x on the left by A twice.)

come 2023, Nigerians will still vote in this same people, especially when they start throwing a cup of rice and sachet tomato paste, you see them queuing, rushing to eat their destinies. we just love suffering n smiling in this country.

You can't blame them if you've not tasted poverty like they had... I just pity this country.

All these in a bid to grant their Fulani colonies from other neighboring countries access into the country and grant them citizenship secretly.

Mtchewww.. Dem all crazy
