Cho b.thức: P= \(\dfrac{x\sqrt{x}-3}{x-2\sqrt{x}-3}-\dfrac{2\left(\sqrt{x}-3\right)}{\sqrt{x}+1}+\dfrac{\sqrt{x}+3}{3-\sqrt{x}}\)

a) Rút gọn P

b)Tính giá trị của A với x=\(14-6\sqrt{5}\)

Cho biểu thức A=\(\dfrac{x\sqrt{x}-3}{x-2\sqrt{x}-3}-\dfrac{2\left(\sqrt{x}-3\right)}{\sqrt{x}+1}+\dfrac{\sqrt{x}+3}{3-\sqrt{x}}\)

a)Rút gọn biểu thức

b) Tính giá trị của A với x=14-\(6\sqrt{5}\)
