Here are two immediate solutions for the solution of x^2+3x+2==0 one is a functional programming approach and the other is based on pattern matching x/.#&/@Solve[x^2+3x+2==0,x] and Solve[x^2+3x+2==0,x]/.{x_->y_}:>y regards yehuda On 4/15/07, JikaiRF at aol.com <JikaiRF at aol.com> wrote: > > Dear Members: > When I use "Solve" in order to solve polynomials with high orders, its > solutions are usually reterned in terms of a pair of nested braces, > like {{x -> 0.1}, {x -> 0.5}}.
