Giải các phương trình sau :
1, 2x (x + 2)\(^2\) - 8x\(^2\) = 2 (x - 2) (x\(^2\) + 2x +4)
2, 8x (x +3 )\(^2\) - 3x = ( x +2)\(^3\) +1
3, \(\dfrac{10x+3}{12}\) = 1 + \(\dfrac{6+8x}{9}\)
4,\(\dfrac{x-23}{24}+\dfrac{x-23}{25}=\dfrac{x-23}{26}+\dfrac{x-23}{27}\)
5,\(\dfrac{x^2-10x-29}{1971}+\dfrac{x^2-10x-27}{1973}=\dfrac{x^2-10x-1971}{29}+\dfrac{x^2-10x-1973}{27}\)
