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 and restores the timeline to what it should have been. A Cube is also given to Guardians of the Galaxy member Star-Lord by time-traveling villain Kang the Conqueror to use against Adam Warlock's evil alter ego, the Magus. However, Magus altered perception to make it seem like the Cube's power was used up. Star-Lord used the Cube's last bit of energy for real by subduing the reborn Thanos, rendering it a "cosmic paperweight". Absorbing Man becomes capable of assimilating the abilities of a fraction of a Cube. He is stopped by criminal mastermind Norman Osborn, who uses a magical sword
