Sorry if this seems a bit basic, I'm pretty new to all this etc. I'm trying to write a programme which can read in real coefficients of a 2nd order polynomial (ax^2 + bx + c = 0) and produce its roots in terms of x1 and x2.. this is what I have so far:

The values for a, b and c I have are:Code:#include<iostream.h> #include<conio.h> #include<stdio.h> #include<math.h> main () { int ia,ib,ic; float a, b, c; float x1, x2; float s1; cout<<"Polynomial task"<<endl; cout<<" "<<endl; cout<<"x1 = -b/2a + sqrt((b^2/4a^2) - c/a)"<<endl; cout<<"x2 = -b/2a - sqrt((b^2/4a^2) - c/a)"<<endl; cout<<" "<<endl; cout<<"Choose a value for a:"<<endl; cin>>ia; if (ia==0) { cout<<"Division by 0 is not possible, please choose another value."<<endl; getch(); return(0); } cout<<"Choose a value for b:"<<endl; cin>>ib; cout<<"Choose a value for c:"<<endl; cin>>ic; a = (float)ia; b = (float)ib; c = (float)ic; s1 = sqrt( ( (ib^2) / (4 * (ia^2)) ) - (c/a) ); if (s1 < 0) { cout<<"No possible solution for these values"<<endl; getch(); return(0); } x1 = -(b / (2*a) ) + s1; cout<<" "<<endl; cout<<"x1 ="<<endl; cout<<x1<<endl; x2 = -(b / (2*a) ) - s1; cout<<" "<<endl; cout<<"x2 ="<<endl; cout<<x2<<endl; getch(); return(0); }

5, 3, -1

-3, 27, 0.5

5, 0, 0

5, 50, 0

1, 4, 4

0, 4, 4

0, 0, 0

0, 2.74, 0

However the values I'm getting when I plug in these coefficients for x1 and x2 are way off the mark. I'm not really sure where I'm going wrong. Any help is appreciated.
