Giải các phương trình sau

6) \(\left(x^2-1\right)^2=4x+1\)

7) \(\left(x^2-9\right)^2=12x+1\)

8) \(\left(x^2+12x+35\right)\left(x^2-4x+3\right)=297\)

9) \(\left(8x+5\right)^2\left(4x+3\right)\left(2x+1\right)=9\)

10) \(\dfrac{x^2}{3}+\dfrac{48}{x^2}=10\left(\dfrac{x}{3}-\dfrac{4}{x}\right)\)

11) \(\dfrac{x^4+4}{x^2-2}=5x\)

12) \(x^4+9=5x\left(x^2-3\right)\)

13) \(\dfrac{2x}{2x^2-5x+3}+\dfrac{13x}{2x^2+x+3}=6\)

14) \(x^2+\dfrac{x^2}{x^2+2x+1}=3\)

15) \(\dfrac{x-49}{50}+\dfrac{x-50}{49}=\dfrac{49}{x-50}+\dfrac{50}{x-49}\)
