    {
        int y, x;
        
        Console.WriteLine("y = x² - 2x +1");
        Console.WriteLine();
        
        for (x=-10; x <= 10; x++)
        {
            y = x*x - 2*x + 1;
            Console.WriteLine(
                "x = {0} ; y=({0})² - 2*({0}) +1 = {1}",
                x, y);
