Best ResponseYou've already chosen the best response.2\[\LARGE (\sqrt x+1)^2=(\sqrt{x+2})^2\] \[\LARGE (\sqrt x)^2+2\cdot \sqrt{x}\cdot 1+1^2=x+2\] \[\LARGE x+2\cdot \sqrt{x}=x+21\] \[\LARGE 2\cdot \sqrt{x}=xx +21\] \[\LARGE 2\cdot \sqrt{x}=1\] \[\LARGE \sqrt{x}=\frac12\] square both sides and there you go :)
