please, can anyone tell me a way to make a size of this matrix smaller because it is out the text in PDF file.

THANK YOU ADVANCE
My suggestion is to simplify the formula: define objects which arise often in the formula in a set of earlier equations, then use the new notation to make the final result compact.
I've not compiled this LaTeX matrix, but, as a general rule, you could reducing the font size.

I would factor out the denominator "\left(-2-2\beta_2\right){}^2".
By the way, I think your LaTeX got a bit mangled when you posted it, e.g.
\begin{document}\right)\\
and a missing "\right)" at the end of the equation. In future, I suggest you add your .tex file as an attachment, and perhaps even sample PDF output.
use the following command before the tabular.
\scalebox{0.6}{%
\begin{tabular}
\end{tabular}}
You can use the following comments:
$\begin{psmallmatrix}
a & b \\
c & d
\end{psmallmatrix}$.
