    Welcome to TeX.SX! Please help us help you and add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{...} and ending with \end{document}. Don't post code as an image! – dexteritas Aug 6 '17 at 19:24

    I have no idea what you're asking. – JPi Aug 6 '17 at 19:28

Try to use amsmath's pmatrix environment instead of tabular, as described in other answers.

\documentclass{article}
\usepackage{amsmath}
\begin{document}

 \begin{equation}
   \begin{pmatrix}
     1 & x_1 & \cdots \\
     \vdots & \vdots & \vdots
   \end{pmatrix}
   \begin{pmatrix}
      a_1 \\
      a_2\\
      \vdots
   \end{pmatrix}
   =
   \begin{pmatrix}
     y_n \\
     f_1 \\
     \vdots
   \end{pmatrix}
 \end{equation)

\end{document}
