#include <iostream>
#include <cmath>
using namespace std;
int main() {
int a, b, c, x, y;
cout << "a : ";
cin >> a;
cout << "b : ";
cin >> b;
cout << "c : ";
cin >> c;
cout << "x : ";
cin >> x;
y = a*pow(x,2) + b*x + c;
cout << "y = " << y;
return 0;
}

To obtain 14 where all <a> <b> <c> and <x> were 2, do ( x * 2 ) rather than ( x ^ 2 )

y = a*(x^2) + b*x + c;

Pro grammer then provide more examples so people can figure out the formula. You only shared one case where everything was 2, who would've known?

Yaroslav Vernigora thanks you.

Ipang right, but 2 was just an example

Yaroslav Vernigora what's the difference? đ§

... b*x+c --->>> ... b*x+c;
cout >> "y=" --->>> cout << "y="

Yaroslav Vernigora yeah, that's right, I fixed it, but it still returns the wrong answer. :(
when I set all values as 2, it returns 6 instead of 14.

so the problem is with your formula. you will need to change it. this is already the field of mathematics. here I am not strong
