Hi, I read that linear combinations of a state, Psi, can be as:

\begin{equation}

\Psi = \alpha \psi + \beta \psi

\end{equation}

where ##\alpha## and ##\beta## are arbitrary constants.

Can however this be a valid linear combination?

\begin{equation}

\Psi = \alpha \psi \times \beta \psi

\end{equation}

Thanks!
