Answer Posted / patel mac p

#include<stdio.h>
#include<conio.h>
#include<math.h>
void main()
{
clrscr();
int a,b,c,d;
float x1,x2,root;
printf("\nEnter the value of a,b,c");
scanf("%d %d %d",&a,&b,&c);
d=(b*b)-(4*a*c);
if(a==0&&b==0)
{
printf("\nNO SOLUTION");
}
else
if(a==0&&b!=0)
{
root=-c/b;
printf("ROOT=%f",root);
}
else
if(d>=0)
{
printf("\nROOTS ARE REAL");
x1=(-b+sqrt(d))/(2*a);
x2=(-b-sqrt(d))/(2*a);
printf("\nX1=%f",x1);
printf("\nx2=%f",x2);
}
else
if(d<0)
{
printf("\nTHIS EQUATION HAS IMAGINARY ROOTS");
}
getch();
}
