Question

Giups m vs 

 

Answer 1

\(=\left(\dfrac{\sqrt{x}\left(\sqrt{x}+3\right)}{\left(\sqrt{x}+3\right)\left(\sqrt{x}-3\right)}-\dfrac{4}{\sqrt{x}\left(\sqrt{x}-3\right)}\right).\left(\dfrac{\sqrt{x}+2+\sqrt{x}-2}{\left(\sqrt{x}-2\right)\left(\sqrt{x}+2\right)}\right)\)

\(=\dfrac{x-4}{\sqrt{x}\left(\sqrt{x}+3\right)}.\left(\dfrac{2\sqrt{x}}{x-4}\right)=\dfrac{2}{\sqrt{x}+3}\)
