Answer

Two real irrational solutions.

Work Step by Step

The standard form of the quadratic equation $\Rightarrow a^2+bx+c=0$ By comparing the given equation and the standard equation we identify $a=3,b=4$ and $c=-2$ The discriminant in the standard form is $b^2-4ac$. Plug all values. $=(4)^2-4(3)(-2)$ Simplify. $=16+24$ $=40$. The discriminant is a positive non perfect square number. Hence, the solutions are two real irrational numbers.
