Thread: Quadratic Equation

So,
For our first lab in computer science we need to come up with a program that solves ALL values inputted into the quadratic equation. (imaginary, infinite etc). I have been gone for most classes thus far due to sports... and am really behind. Can anyone satisfy this and then explain it? I'mreally lost. this is wht i have so far
include <FPT.h>
int main()
{
double a,b,c,x1,x2;
a=inD() ; b=inD() ; c=inD();
if (a==0 && b==0 && c==0)
{
outS ("There are infinite solutions");
else {
