Question

Ajutor va rog,ajutati sa aflu rezolvarea si va rog explicati!!! Dau coroana

Answer 1

Program f;

uses crt;

var a,b,c,d,x1,x2:real;

begin

write('introdu a=');readln(a);

write('introdu b=');readln(b);

write('introdu c=');readln(c);

d:=b*b-4*a*c;

if d>0 then

begin

 x1:=(-b+sqrt(d))/2*a;

 x2:=(-b-sqrt(d))/2*a;

 Writeln('X1=',x1);

 Writeln('X2=',x2);

end

else

Writeln('nu are radacina!!!');

Readkey; sau readln;

end.

Answer 2

#include <iostream>

#include <cmath>

#include <iomanip>

using namespace std;

int main()

{

   float a,b,c,x1,x2,d;

   cin>>a>>b>>c;

   d=b*b-4*a*c;

   if(d<0)

       cout<<"Nu are solutii reale";

   else

       if(d==0)

   {

       x1=(-b)/(2*a);

       cout<<"Radacina dubla "<<fixed<<setprecision(2)<<x1;

   }

   else

   {

       x1=(-b+sqrt(d))/(2*a);

        x2=(-b-sqrt(d))/(2*a);

        cout<<fixed<<setprecision(2)<<x1<<" "<<x2;

   }

   return 0;
