Answer 1

\(\Leftrightarrow\left[{}\begin{matrix}x=0\\x+5=0\end{matrix}\right.\\ \Leftrightarrow\left[{}\begin{matrix}x=0\\x=-5\end{matrix}\right.\)

Answer 2

`x*(x+5)=0`

\(=>\left[{}\begin{matrix}x=0\\x+5=0\end{matrix}\right.\\ =>\left[{}\begin{matrix}x=0\\x=-5\end{matrix}\right.\)

Answer 3

\(x\left(x+5\right)=0\)

\(\Leftrightarrow\left[{}\begin{matrix}x=0\\x=-5\end{matrix}\right.\)

Answer 4

\(x.\left(x+5\right)=0\)

\(=>\left[{}\begin{matrix}x=0\\x+5=0\end{matrix}\right.=>\left[{}\begin{matrix}x=0\\x=-5\end{matrix}\right.\)
