Well... You know, there's a cpp book right there...

@Daleth
which book you r talking about
can you tell me the code to solve it

[Ispil]

Think about it. It gives you the formula, and what is put into the formula... now what do you do in code that involves plugging values in?

// For the positive root, try
double root1 = (-b + sqrt(b*b - 4*a*c))/(2*a);

Grab any first-course C++ text, the first few chapters will show you how to tackle this pretty basic problem. Good luck
