Question

sqrt x+2+sqrt x=4

Answer 1

and just what are we sposed to do with it?

Answer 2

guess at what it is sposed to mean?

Answer 3

\[\sqrt{x+2+\sqrt{x}} = 4\]

Answer 4

\[\sqrt{x+2}+\sqrt{x}=4 \] square both sides
\[(\sqrt{x+2}+\sqrt{x})^2=16 \rightarrow x+2+2(\sqrt{x+2})(\sqrt{x}) \rightarrow x+2+2(\sqrt{x^2+2x})\]
