\(Q=\frac{2x+2\sqrt{x}+2}{-\sqrt{x}}+\sqrt{x}\)
\(Q=-2\sqrt{x}-2-\frac{2}{\sqrt{x}}+\sqrt{x}\)
\(Q=-\sqrt{x}-\frac{2}{\sqrt{x}}-2\)
\(\sqrt{x}+\frac{2}{\sqrt{x}}\ge2\sqrt{2}\Rightarrow-\left(\sqrt{x}+\frac{2}{\sqrt{x}}\right)\le-2\sqrt{2}\)
\(\Rightarrow Q\le-2\sqrt{2}-2\)
\("="\Leftrightarrow x=\sqrt{2}\)
