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
Cosmic Cube the trio invaded a KubeKult base to steal the erratically functioning Cube but the Red Skull seized it and willed Captain America to be drawn inside it into an artificial reality during World War II, where Captain America and Bucky were on a mission to kill Hitler. The Red Skull believed that he would be able to wield the Cube's power only if Captain America killed Hitler's consciousness within the Cube. However, the Bucky within the Cube (actually a projection of Cap's own mind) revealed what was really going on and Captain America was able to will himself out of
