Assuming \(x\in \mathbb{R}\), find the solution set of the following equation.
\[
\left (3x + 2\right )\left (x\sqrt{2} + 1\right )\left (x^{2} + 1\right ) = 0
\]
\(\left \{-\frac{\sqrt{2}}
{2} ;-\frac{2}
{3}\right \}\)
\(\left \{-\frac{2}
{3}; \frac{1}
{\sqrt{2}}\right \}\)
\(\left \{\frac{2}
{3}; \frac{1}
{\sqrt{2}}\right \}\)
\(\left \{-1;-\frac{\sqrt{2}}
{2} ;-\frac{2}
{3}\right \}\)
