akar-akar persamaan kuadrat



dalam c++

#include <iostream>
#include <math.h>
using namespace std;

main(){
float x1,x2,a,b,c,rms;
cout<<"----menghitung akar-akar pers kuadrat----"<<endl;

cout<<"masukan nilai A = "; cin>>a;
cout<<"masukan nilai B = "; cin>>b;
cout<<"masukan nilai C = "; cin>>c;

rms=b*b-4*a*c;

if(rms==0 ){
x1=-b/(2*a);
x2=x1;
}
else if(rms>0){
x1= -b+((sqrt(rms))/(2*a));
x2= -b-((sqrt(rms))/(2*a));
}
else if(rms<0) {
cout<<"akar imajiner";
}

cout<<"nilai akar"<<endl;
cout<<"x1= "<<x1<<endl;
cout<<"x2= "<<x2;
