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
Cube Cove, Alaska Cube Cove, Alaska Cube Cove was an unincorporated community and census-designated place on the northwestern side of Admiralty Island in the Hoonah-Angoon Census Area of the U.S. state of Alaska.
