Root-finding algorithm cubic polynomial may involve non-real cube roots). For polynomials of degree five or higher Abel–Ruffini theorem asserts that there is, in general, no radical expression of the roots. So, except for very low degrees, root finding of polynomials consists of finding approximations of the roots. By the fundamental theorem of algebra, one knows that a polynomial of degree has at most real or complex roots, and the this number is reached for almost all polynomials. It follows that the problem of root finding for polynomials may be split in three different subproblems; For finding one root, Newton's method and other
The Cube (film) joke. Enraged, he tells them he's had enough with their tricks and that no matter what happens he knows he is real. The Man then leaves the Cube as the people applaud him. The Man is then escorted into an office so that the head of the organization can sign his release. Once there, the Man reflects on the revelation of his own realness. He accidentally cuts himself with a knife while demonstrating and is asked to taste his blood. He does so and discovers his blood is strawberry jam. The head of the organization and the office fades away
