To write a java program that prints all real solutions of the expression ax2+bx+c=0.
Program:
import java.io.*;
class Qexp
{
public static void main(String arg[])
{
double a=5,b=2,c=3;
double d,x1,x2;
d=b*b-4*a*c;
if(d<0)
{
System.out.println("Roots are imaginary");
}
else
{
x1=(-b+Math.sqrt(d))/(2*a);
x2=(-b-Math.sqrt(d))/(2*a);
System.out.println("x1=" + x1 + " x2=" + x2);
}
}
}
Input & Output Analysis:-
Roots are imaginary
