Answer 3

\(\Large \sqrt { 2x+4 } -\sqrt { x } =2\\ \Large \Rightarrow \sqrt { 2x+4 } =2+\sqrt { x } \\ \Large \Rightarrow 2x+4=({ 2+\sqrt { x } })^{ 2 }\\ \Large \Rightarrow 2x+4=4+4\sqrt { x } +x\\ \Large \Rightarrow 4\sqrt { x } =x\\ \Large\Rightarrow 16x={ x }^{ 2 }\\ \Large\Rightarrow { x }^{ 2 }-16x=0\\ \Large \Rightarrow \begin{cases} x=0 \\ x=16 \end{cases}\)
