Có \(\left(\sqrt{x+2}-\sqrt{x-2}\right)\left(1+\sqrt{x^2+7x+10}\right)=3\)
suy ra \(\left(\sqrt{x+2}-\sqrt{x-2}\right)\left(\sqrt{x+2}+\sqrt{x-2}\right)\left(1+\sqrt{x^2+7x=10}\right)=3\left(\sqrt{x+2}+\sqrt{x-2}\right)\)
\(4\left(1+\sqrt{\left(x+2\right)\left(x+5\right)}\right)=3\left(\sqrt{x+2}+\sqrt{x-2}\right)\)
