ĐKXĐ: \(x\ge-2\)
\(\Leftrightarrow\sqrt{x+2}-2+\sqrt{x+7}-3+x-2\le0\)
\(\Leftrightarrow\frac{x-2}{\sqrt{x+2}+2}+\frac{x-2}{\sqrt{x+7}+3}+x-2\le0\)
\(\Leftrightarrow\left(x-2\right)\left(\frac{1}{\sqrt{x+2}+2}+\frac{1}{\sqrt{x+7}+3}+1\right)\le0\)
\(\Leftrightarrow x-2\le0\)
\(\Rightarrow-2\le x\le2\)
