Question

Ecuatia de gradul 2 :ax2+bx+c=0 in c++,va rog?

Answer 1

#include<iostream.h>
#include<math.h>
using namespace std;
int main()
{int a,b,c;
float x1,x2,delta;
cout<<"a="; cin>>a;
cout<<"b="; cin>>b;
cout<<"c="; cin>>c;
if(a==0)
   cout<<"Ecuatie de gradul I"<<endl;
else
{delta = b*b-4*a*c;
if(delta>0)
{x1=(-b-sqrt(delta)) / (2*a);
x2=(-b+sqrt(delta)) / (2*a);
cout<<"Ecuatia are doua radacini reale"<<endl;
cout<<"x1="<<x1<<endl;
cout<<"x2="<<x2<<endl; }
else
if(delta==0)
{cout<<Ecuatia are doua radacini reale"<<endl;
cout<<"x1=x2="<< -b/(2*a)<<endl; }
else
cout<<"Ecuatia are doua radacini complexe"<<endl; }
return 0; }

Answer 2

dc nu vr sa faci cum am spus
