Answer 1

#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;
}

Answer 2

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

Answer 3

#include <iostream>
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*(x^2) + b*x + c;
cout << "y = " << y;
return 0;
}

Answer 4

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?

Answer 5

Yaroslav Vernigora thanks you.

Answer 6

Ipang right, but 2 was just an example

Answer 7

#Include <math.h>

Answer 8

Yaroslav Vernigora what's the difference? 🧐

Answer 9

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

Answer 10

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.

Answer 11

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

Answer 12

Thank you guys, It was really helpful.
