Giải các phương trình sau: 3(x - 2)^2 + 9(x - 1) = 3(x^3 + x - 3)

$$\begin{gathered} 3{\left(\mathrm{x}-2\right)}^2+9\left(\mathrm{x}-1\right)=3\left({\mathrm{x}}^3+\mathrm{x}-3\right) \\ 11\mathrm{x}+42-2\mathrm{x}=100-9\mathrm{x}-22 \\ 8\left(3\mathrm{x}-2\right)-14\mathrm{x}=2\left(4-7\mathrm{x}\right)+19\mathrm{x} \\ 12-2\left(\mathrm{x}-1\right)=\mathrm{x}{\left(\mathrm{x}-2\right)}^2-5{\mathrm{x}}^3 \\ 2{\mathrm{x}}^2+{\left(\mathrm{x}+5\right)}^2-2{\left(\mathrm{x}+7\right)}^2=2\left(3\mathrm{x}+72,5\right)-{\left(\mathrm{x}-6\right)}^2 \end{gathered}$$
