HELP!..PLEASE..i have a project that asks to write a C++ program solving for the root of the equation (x*x*x)-(x*x)-(9x)+(9) ........huhuhu..please help..i really need to pass..please..

mmm i just want to know
is that program have to provide a choice for a user to solve any equation with any degree ,, or just with the degree 3 as u post !!

anyway .. as i think it's similar to that problem i have posted before ..
have alook at it

Now you need to use a numerical method for solving the equation.
Bisection, Newton raphson etc. Get the algorithm for one of them, understand it(if you can), and transform the algorithm into c++ code.
