$${y}=\frac{\mathrm{3}{x}^{\mathrm{2}} −\mathrm{1}}{\mathrm{9}} \\ $$$${x}^{\mathrm{4}} −\frac{\mathrm{2}{x}^{\mathrm{2}} }{\mathrm{3}}−\mathrm{27}{x}+\frac{\mathrm{1}}{\mathrm{9}}=\mathrm{0} \\ $$$$\mathrm{No}\:\mathrm{nice}\:\mathrm{solution} \\ $$$${x}\approx.\mathrm{00411480}\wedge{y}\approx−.\mathrm{111105} \\ $$$${x}\approx\mathrm{3}.\mathrm{07275}\wedge{y}\approx\mathrm{3}.\mathrm{03616} \\ $$$${x}\approx−\mathrm{1}.\mathrm{53843}\pm\mathrm{2}.\mathrm{53397i}\wedge{y}\approx−\mathrm{1}.\mathrm{46253}\mp\mathrm{2}.\mathrm{59890i} \\ $$ | ||
