The innovative conceit of the method is direct finding 2 real roots, in the form of 2 fractions, knowing their sum (-b/a) and their product (c/a). It is a trial and error method, same as the factoring one, but it has fewer permutations. It is fast, convenient and applicable whenever the quad. equation can be factored.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4172814789229843414.post-75816884801594106382010-03-04T16:49:34.966+05:302010-03-04T16:49:34.966+05:30This comment has been removed by a blog administrator.Ella Rogersnoreply@blogger.com
