ABSTRACT: We give a formula for cyclic homology for free algebras which is used to compute cyclic homology of global dimension two algebras, in particular a free algebra modulo a symmetric quadratic form or not too many general symmetric quadratic forms which using Koszul duality gives a formula for the cyclic homology of a commutaive polynomial ring modulo sufficiently many quadratic relations.
