RÚT GỌN GIÚP EM VỚI Ạ, EM CẢM ƠN MỌI NGƯỜI NHIỀU

Answer 1

\(H=\dfrac{x+5\sqrt{x}+6+x-3\sqrt{x}+2-4\sqrt{x}+4}{\left(\sqrt{x}-2\right)\left(\sqrt{x}+2\right)}:\dfrac{\sqrt{x}-2+5}{\sqrt{x}-2}\)

\(=\dfrac{2x-2\sqrt{x}+12}{\sqrt{x}+2}\cdot\dfrac{1}{\sqrt{x}+3}\)

\(I=\dfrac{3x+3-2x+6\sqrt{x}-x-3\sqrt{x}}{x-9}:\dfrac{2\sqrt{x}-2-\sqrt{x}+3}{\sqrt{x}-3}\)

\(=\dfrac{3\left(\sqrt{x}+1\right)}{\left(\sqrt{x}-3\right)\left(\sqrt{x}+3\right)}\cdot\dfrac{\sqrt{x}-3}{\sqrt{x}+1}=\dfrac{3}{\sqrt{x}+3}\)
