I have a quintic function (5th degree polynomial), and I would like to solve it in C ++. Is there an implementation or math library that I can use to continue?
Perhaps this may solve your problem: http://www.gnu.org/software/gsl/manual/html_node/General-Polynomial-Equations.html
Boost has it. Look at here:
