3\left(x+1\right)^{2}=-2
Subtracting 2 from itself leaves 0.
\frac{3\left(x+1\right)^{2}}{3}=-\frac{2}{3}
Divide both sides by 3.
\left(x+1\right)^{2}=-\frac{2}{3}
Dividing by 3 undoes the multiplication by 3.
x+1=\frac{\sqrt{6}i}{3} x+1=-\frac{\sqrt{6}i}{3}
Take the square root of both sides of the equation.
x+1-1=\frac{\sqrt{6}i}{3}-1 x+1-1=-\frac{\sqrt{6}i}{3}-1
Subtract 1 from both sides of the equation.
x=\frac{\sqrt{6}i}{3}-1 x=-\frac{\sqrt{6}i}{3}-1
Subtracting 1 from itself leaves 0.
