Question
Find roots of polynomial $$ p(x) = 18x-16 $$
Answer
The root of polynomial $ p(x) $ is:
$$ \begin{aligned}x &= \dfrac{ 8 }{ 9 } \end{aligned} $$Explanation
$$ \begin{aligned} 18x-16 & = 0 \\[1 em]
18 \cdot x & = 16 \\[1 em]
x & = \frac{ 16 }{ 18 } \\[1 em]
x & = \frac{ 16 : 2 }{ 18 : 2} \\[1 em]
x & = \frac{ 8 }{ 9 }
\end{aligned} $$
