Solve for x, y
x=1\text{, }y=2
x=\frac{-4\left(\sqrt{22}\cos(\frac{\arccos(\frac{173\sqrt{22}}{968})}{3})-1\right)^{2}+45}{9}\approx -0.772865558\text{, }y=\frac{2\left(\sqrt{22}\cos(\frac{\arccos(\frac{173\sqrt{22}}{968})}{3})-1\right)}{3}\approx 2.40267883
x=\frac{-\left(\sqrt{22}\cos(\frac{\arccos(\frac{173\sqrt{22}}{968})}{3})+\sqrt{66}\sin(\frac{\arccos(\frac{173\sqrt{22}}{968})}{3})+2\right)^{2}+45}{9}\approx -2.391382381\text{, }y=\frac{-\sqrt{22}\cos(\frac{\arccos(\frac{173\sqrt{22}}{968})}{3})-\sqrt{66}\sin(\frac{\arccos(\frac{173\sqrt{22}}{968})}{3})-2}{3}\approx -2.71870969
x=\frac{-\left(\sqrt{66}\sin(\frac{\arccos(\frac{173\sqrt{22}}{968})}{3})-\sqrt{22}\cos(\frac{\arccos(\frac{173\sqrt{22}}{968})}{3})-2\right)^{2}+45}{9}\approx 2.164247938\text{, }y=\frac{\sqrt{66}\sin(\frac{\arccos(\frac{173\sqrt{22}}{968})}{3})-\sqrt{22}\cos(\frac{\arccos(\frac{173\sqrt{22}}{968})}{3})-2}{3}\approx -1.683969139
