giải hộ mk bài này nha????

giải phương trình :

1)\(5\left(\frac{x^2-4}{x^2-1}\right)-\left(\frac{x+2}{x-1}\right)^2-\left(\frac{x-2}{x+1}\right)^2=0\)

2)\(x^2+\left(\frac{x}{x-1}\right)^2=8\)

3)\(x^2+\left(\frac{81x^2}{\left(x+9\right)^2}\right)=40\)

4)\(\frac{\left(x-1\right)^2}{x^2}+\frac{\left(x-1\right)^2}{\left(x-2\right)^2}=\frac{40}{49}\)

5)\(\left(\frac{x}{x+1}\right)^2+\left(\frac{x}{x-1}\right)^2=90\)
