Question

Elaborati o procedura care: sa calculeze radacinile ecuatii axpatrat+bx+c egal cu zero

a x^{2} +bx+c egal cu 0

Answer 1

int a,b,c,delta,x1,x2;
cin>>a;
cin>>b;
cin>>c;
if(a==0) cout<<"Nope, nu e de gradul 2";
else{
delta = b*b + 4*a*c;
x1 = (-b + sqrt(delta))/(2*a);
x2 = (-b - sqrt(delta))/(2*a);
cout<<"x1="<<x1<<endl;
cout<<"x2="<<x2;
}
