\[\left( {\begin{array}{*{20}{c}}
8 & { - 1} \\
{ - 34} & 6 \\

\end{array} } \right)\]

Removing the \[ \] and replacing with [math] [/math] delimiters:

$\left( \begin{array}{*{20}{cc}} 8 & { - 1} \\ { - 34} & 6 \\\end{array} \right)$

Code:

\int_0^{2\pi} \kappa(s) ds = \int d\theta = \theta + c

gives

$\int_0^{2\pi} \kappa(s) ds = \int d\theta = \theta + c$
