Rút gọn biểu thức sau
\(A=\frac{\sqrt{x-3}}{\sqrt{x-2}}-\frac{2\sqrt{x-1}}{\sqrt{x-1}}+\frac{x-2}{x-2\sqrt{x+}2}\)
Rút gọn biểu thức sau
\(A=\frac{\sqrt{x+2}}{\sqrt{x-3}}-\frac{\sqrt{x+1}}{\sqrt{x-2}}-\frac{3\sqrt{x-3}}{x-5\sqrt{x+6}}\)
Cho biểu thức \(A=\frac{x^2+\sqrt{x}}{x-\sqrt{x}+1}+1-\frac{2x+\sqrt{x}}{\sqrt{x}}\)
a. Rút gọn A b. Tìm x để A=2
