Solving for an matrix containing complex numbers

59 Views Asked by At

$$Ax = 0$$

$$A x= \begin{bmatrix}-6 -2i & 5\\0& 0\end{bmatrix} \begin{bmatrix}x_1\\x_2\end{bmatrix} = \begin{bmatrix}0\\0\end{bmatrix}$$

Simple question, but how do I solve for $x_1$ and $x_2$?

One potential answer is:

$$\begin{bmatrix}x_1\\x_2\end{bmatrix} = \begin{bmatrix}-1+2i\\-2+2i\end{bmatrix}$$

I'm not sure how to get a result like this with complex numbers though. Can I get a detailed explanation on how to do this?

Let $x_1=-6+2i$

$$(-6-2i)(-6+2i)+5x_2=0$$

$$36-(2i)^2+5x_2=0$$

$$40+5x_2=0$$

$$x_2=-8$$
