I am solving an exercise on multiple linear regression. Near the end I will be asked for the same data as the previous model, it is the maximum likelihood estimates.

The previous model:
     I have the matrix $(X'X)^{-1}$ and the matrix $X'y$ and the model is:

   $Y_i = B_0 + B_1x_i + B_2x^2_i + e_i$   

$i= 1,...,10$

Now I have: 
     
  $Y_i = g_0 + g_1x^*_i + g_2(x^*_i)^2 + e_i$ 
     
  $ x^*_i = x_i -10$ 
  
  $i=1,...,10$
   
To transform the model can I decrease the Matrix data for 10?

For example the first row of the matrix $(X'X)^{-1}$ is:
$[4,0,0]$   
$4-10;0-10;0-10 ....$

The same thing can I make it also for the matrix $X'y$?
Perhaps the question is stupid, but wants to be sure of this solution.
Thank you.
