Question
Find roots of polynomial $$ p(x) = 2x-6 $$
Answer
The root of polynomial $ p(x) $ is:
$$ \begin{aligned}x &= 3 \end{aligned} $$Explanation
$$ \begin{aligned} 2x-6 & = 0 \\[1 em]
2 \cdot x & = 6 \\[1 em]
x & = \frac{ 6 }{ 2 } \\[1 em]
x & = \frac{ 6 : 2 }{ 2 : 2} \\[1 em]
x & = 3
\end{aligned} $$
