Pennsylvania Route 343 community of Bordnersville soon after. The highway was then extended along the local continuation to end at US 22 in Harper Tavern. In 1963, PA 343 was moved back to Lickdale, and seven years after, moved to its northern terminus, thirteen years after the construction of I-78. PA 343 begins at an intersection with PA 72, near the Northwest Elementary School, in the city of Lebanon in Lebanon County. PA 343 heads eastward along Maple Street, a two-lane undivided street maintained by the city, past urbanized homes and businesses. The route turns north onto North 7th Street and passes more
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
