`(1/(x-\sqrt{x})+1/(x-1)):(\sqrt{x}+1)/(x-2\sqrt{x}+1) ` Đk:  `x >= 0` ; `x \ne 1`

`=[(\sqrt{x}+1)/(\sqrt{x}(x-1))+(\sqrt{x})/(\sqrt{x}(x-1))]*(x-2\sqrt{x}+1)/(\sqrt{x}+1)`

`=(2\sqrt{x}+1)/(\sqrt{x}(x-1))*(x-2\sqrt{x}+1)/(\sqrt{x}+1)`

`=(2\sqrt{x}+1)/(\sqrt{x}(x-1))*((\sqrt{x}-1)^2)/(\sqrt{x}+1)`

`=((2\sqrt{x}+1)(\sqrt{x}-1))/(\sqrt{x}(\sqrt{x}+1)^2`

`=-(\sqrt{x}-2x+1)/(\sqrt{x}(\sqrt{x}+1)^2`
