Evaluate (complex solution)
Y=x\left(3x+2\right)\text{ and }\left(x=\frac{\sqrt{31}-1}{3}\text{ or }x=\frac{-\sqrt{31}-1}{3}\right)
Solve for x
x = \frac{-\sqrt{31} - 1}{3} = -2.189254787610007
x=\frac{\sqrt{31}-1}{3}\text{, }Y=10
Solve for Y
Y=10
x=\frac{\sqrt{31}-1}{3}\text{ or }x=\frac{-\sqrt{31}-1}{3}
