PolynomialRegression.ToString returns the wrong coefficients

What steps will reproduce the problem?
1.PolynomialRegression poly = new PolynomialRegression(2);
  var x = new double[] {0,  1,  2,  3,  4,  5,  6,   7,   8,   9,   10};
  var y = new double[] {1,  6,  17, 34, 57, 86, 121, 162, 209, 262, 321};
  poly.Regress(x, y);
  Console.WriteLine("Fit  ={0}", poly.ToString());

What is the expected output? What do you see instead?
Expected: y(x) = 1.00000000000005*x^0 + 1.99999999999998*x^1 + 3*x^2
Actual:   y(x) = 3*x^0 + 1.99999999999998*x^1 + 1.00000000000005*x^2

What version of the product are you using? On what operating system?
2.8.1.0 for .Net 4
Windows 7
