Question
Find roots of polynomial $$ p(x) = 8s-4 $$
Answer
The root of polynomial $ p(s) $ is:
$$ \begin{aligned}s &= \dfrac{ 1 }{ 2 } \end{aligned} $$Explanation
$$ \begin{aligned} 8s-4 & = 0 \\[1 em]
8 \cdot s & = 4 \\[1 em]
s & = \frac{ 4 }{ 8 } \\[1 em]
s & = \frac{ 4 : 4 }{ 8 : 4} \\[1 em]
s & = \frac{ 1 }{ 2 }
\end{aligned} $$
