## If $p\neq 0$, then there are $x_+$ and $x_-$ with $x_\pm ^2=p$ , $p\in \mathbb{C}$.

If $$p\neq 0$$, then there are $$x_+$$ and $$x_-$$ with $$x_\pm ^2=p$$ , $$p\in \mathbb{C}$$.

Hello,

I guess case-by-case analysis with $$p\in \mathbb{R}$$ and $$p\in \mathbb{C}\backslash \mathbb{R}$$.

But I don’t even know how to start.
