// using sqrt in the program it needs header file <math.h>
#include<stdio.h>
#include<conio.h>
#include<math.h>
void main()
{
float a,b,c,delta,alpha,beta;
clrscr();

printf("\nENTER THE VALUE OF a:");
scanf("%f",&a);
printf("\nENTER THE VALUE OF b:");
scanf("%f",&b);
printf("\nENTER THE VALUE OF c:");
scanf("%f",&c);

delta=(b*b)-(4*a*c);

if(delta>0)
{
alpha=(-b-sqrt(delta))/(2.0*a);
beta=(-b+sqrt(delta))/(2.0*a);
printf("\nalpha=%f",alpha);
printf("\nbeta=%f",beta);

}
else if(delta==0)
{
printf("\nROOTS ARE REAL");
alpha=-b/(2.0*a);
beta=-b/(2.0*a);
printf("\nalpha=%f",alpha);
printf("\nbeta=%f",beta);
}
else
{
printf("\nROOTS ARE IMAGINARY");
}
getch();
}
