# why symbolic matrix is not properly displayed in LaTeX?

I'm not able to get the output of this matrix in clear way, is poorly displayed, what to do?

\documentclass{article}
\usepackage{amsmath}
\begin{document}
$$G(s)=\begin{bmatrix} \frac{1.24}{s^3 + 0.9215 s^2 + 4.413 s + 3.617} & 0 \\ \frac{1.482 s + 0.4243}{s^4 + 6.333s^3 + 7.083s^2 + 2.083s} & \frac{3.6}{s^3 + 6 s^2 + 5 s} \end{bmatrix}$$
\end{document}


I am not sure how you want to make it "better" but I suggest using \dfrac to put the fractions into "display mode" and adding extra space between the rows by adding \\[4mm] at the end of the first row. This gives:
\documentclass{article}
$$G(s)=\begin{bmatrix} \dfrac{1.24}{s^3 + 0.9215 s^2 + 4.413 s + 3.617} & 0 \\[4mm] \dfrac{1.482 s + 0.4243}{s^4 + 6.333s^3 + 7.083s^2 + 2.083s} & \dfrac{3.6}{s^3 + 6 s^2 + 5 s} \end{bmatrix}$$
