#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 )

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?

... 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
