$$\left({x}+\mathrm{2}\right)\left({x}^{\mathrm{2}} +\mathrm{1}\right)\left({x}^{\mathrm{2}} +{x}+\mathrm{6}\right)\left({x}^{\mathrm{2}} −{x}−\mathrm{1}\right)=\mathrm{0} \\ $$$${x}=−\mathrm{2}\:\vee\:{x}=\frac{\mathrm{1}\pm\sqrt{\mathrm{5}}}{\mathrm{2}}\:\vee\:{x}=\pm\mathrm{i}\:\vee\:{x}=−\frac{\mathrm{1}\pm\sqrt{\mathrm{23}}\mathrm{i}}{\mathrm{2}} \\ $$
