I read your image as $\displaystyle \left|\begin{array}{ccc}x&0&0\\0&x&0\\0&0&x\end{ar ray}\right|=0$, which I'm not sure what to do with (x=0?). Could you perhaps clarify and maybe someone will be able to help?
The determinant of a diagonal matrix is just the product of the numbers on the diagonal.
