Answer

$$x=-\frac{2}{3} \text{ and } x=1$$

Work Step by Step

Factor the trinomial to obtain: $$(3x+2)(x-1)=0$$ Use the Zero-Product Property by equating each factor to zero, then solve each equation to obtain: \begin{align*} 3x+2&=0 &\text{or}& &x-1=0\\ 3x&=-2 &\text{or}& &x=1\\ \frac{3x}{3}&=\frac{-2}{3} &\text{or}& &x=1\\ x&=-\frac{2}{3} &\text{or}& &x=1\\ \end{align*} Thus, the solutions are $x=-\frac{2}{3}$ and $x=1$.
