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:  
\begin{align}
Y_i &= B_0 + B_1x_i + B_2x^2_i + e_i  \\
i &= 1,...,10
\end{align}

Now I have: 

\begin{align}
Y_i &= g_0 + g_1x^*_i + g_2(x^*_i)^2 + e_i  \\
x^*_i &= x_i -10  \\
i &= 1,...,10
\end{align}
 
To transform the model, can I decrease the matrix data for 10? For example the first row of the matrix $(X'X)^{-1}$ is:

$$
[4,\hspace{12mm} 0,\hspace{12mm} 0]\hspace{20mm}   \\
4-10,\ 0-10,\ 0-10,\ ...
$$

The same thing can I make it also for the matrix $X'y$?

------------------------------------------------------------------

I have many doubts. I am publishing the text so it is more understandable.

Consider the regression model linear:

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

with $e_1, ...., e_n$ independent and identically distributed random variables and $x_i,\ i = 1, ..., 0$ constant fix.

The only data I have are these: https://s32.postimg.org/o20r1i5et/Immagine.png. I have to rewrite the whole thing, so I tried:

\begin{align}
(X) &= 
  \begin{bmatrix}
    1 & x_1 & x^2_1\\
    . & . & . \\
    . & . & . \\
    . & . & . \\
    1 & x_{10} & x^2_{10}\\
  \end{bmatrix}  \\[10pt]
(X^*) &= 
  \begin{bmatrix}
    1 & x_1-10 & (x_{1}-10)^2\\
    . & . & . \\
    . & . & . \\
    . & . & . \\
    1 & x_{10}-10 & (x_{10}-10)^2\\
  \end{bmatrix}  \\[10pt]
X^{*'}X^* &= 
  \begin{bmatrix}
    10 & \sum_{i=1}^{10} x_i-10 & \sum_{i=1}^{10}(x_{i}-10)^2\\
    \sum_{i=1}^{10} x_i-10 & \sum_{i=1}^{10} (x_{i}-10)^2 & \sum_{i=1}^{10}(x_{i}-10)^3\\
     \sum_{i=1}^{10} (x_{i}-10)^2 & \sum_{i=1}^{10}(x_{i}-10)^3 & \sum_{i=1}^{10}(x_{i}-10)^4\\
  \end{bmatrix}  \\
\end{align}

Now do I have to calculate the inverse? Am I following the proper solution? Do I have to use the property for equivariance?
