It's a lot easier than you might think.
Take for instance (x+2)^2.
If you set u1 = -1 and sigma1 = 1 you will get the answer.
The coefficient outside of the squared term is 1/1 or 1 which gives sigma1 = 1 and inside the squared term you get (x - -2) = (x+2) which means u1 = 1.
See if you can do the same for the other square term and then later for the correlation coefficient.
