The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= \frac{ 1 }{ 2 }\\[1 em]x_2 &= \frac{ 1 }{ 6 } \end{aligned} $$Step 1:
Get rid of fractions by multipling equation by $ \color{blue}{ 2 } $.
$$ \begin{aligned} 6x^2-4x+\frac{1}{2} & = 0 ~~~ / \cdot \color{blue}{ 2 } \\[1 em] 12x^2-8x+1 & = 0 \end{aligned} $$Step 2:
The solutions of $ 12x^2-8x+1 = 0 $ are: $ x = \dfrac{ 1 }{ 6 } ~ \text{and} ~ x = \dfrac{ 1 }{ 2 }$.
