rút gọn cho mình với ;-;

Đáp án+Giải thích các bước giải:

`P=(1-\frac{\sqrt{x}}{1+\sqrt{x}}):(\frac{\sqrt{x}+3}{\sqrt{x}-2}+\frac{\sqrt{x}+2}{3-\sqrt{x}}+\frac{\sqrt{x}+2}{x-5\sqrt{x}+6})(x≥0;x\ne4;x\ne9)`

`P=(\frac{1+\sqrt{x}-\sqrt{x}}{1+\sqrt{x}}):(\frac{\sqrt{x}+3}{\sqrt{x}-2}-\frac{\sqrt{x}+2}{\sqrt{x}-3}+\frac{\sqrt{x}+2}{(\sqrt{x}-3)(\sqrt{x}-2)})`

`P=\frac{1}{\sqrt{x}+1}:(\frac{(\sqrt{x}+3)(\sqrt{x}-3)-(\sqrt{x}+2)(\sqrt{x}-2)+\sqrt{x}+2}{(\sqrt{x}-3)(\sqrt{x}-2)})`

`P=\frac{1}{\sqrt{x}+1}:(\frac{x-9-x+4+\sqrt{x}+2}{(\sqrt{x}-3)(\sqrt{x}-2)})`

`P=\frac{1}{\sqrt{x}+1}:\frac{\sqrt{x}-3}{(\sqrt{x}-3)(\sqrt{x}-2)}`

`P=\frac{1}{\sqrt{x}+1}:\frac{1}{\sqrt{x}-2}`

`P=\frac{1}{\sqrt{x}+1}.\frac{sqrt{x}-2}{1}`

`P=\frac{\sqrt{x}-2}{\sqrt{x}+1}`
