Write the program to find the roots of quadratic equations.

 Write the program to find the roots of quadratic 
equations.






#include<stdio.h>
#include<conio.h>
#include<math.h>
void main( )
{
            int a,b,c,d;
float x,y;
printf(“Enter a,b,c”);
scanf(“%d %d %d”, &a, &b, &c);
d = b*b-4*a*c;
if(d = = 0)
{
x = -b/2*a;
printf(“Roots are same %.3f %.3f”, x, x);
}
else
{
if(d>0)
{
x = (-b+sqrt(d))/(2*a);
y = (-b-sqrt(d))/(2*a);
printf(“Roots are real %.3f %.3f”,x ,y);
}
else
printf(“Roots are imaginary”);
}
getch( );
}




Output:-
Enter a, b, c 5, 7, 8
Roots are imaginary 1.053565
