Câu hỏi: Rút gọn: \(P = \left( {\frac{{\sqrt x  + 1}}{{\sqrt x  - 1}} + \frac{{\sqrt x }}{{2 + \sqrt x }} - \frac{{4x + 2\sqrt x  - 4}}{{x - 4}}} \right)\left( {\frac{2}{{2 - \sqrt x }} - \frac{{\sqrt x  + 3}}{{2\sqrt x  - x}}} \right)\)

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

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

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

D \(P=\frac{2(x-2\sqrt{x}+2)(\sqrt{x}-7)}{\sqrt{x}(\sqrt{x}-1)(\sqrt{x}-2)}\)
