Question
Find roots of polynomial $$ p(x) = -365x+20000 $$
Answer
The root of polynomial $ p(x) $ is:
$$ \begin{aligned}x &= \dfrac{ 4000 }{ 73 } \end{aligned} $$
Explanation
$$ \begin{aligned} -365x+20000 & = 0 \\[1 em]
-365 \cdot x & = -20000 \\[1 em]
x & = - \frac{ 20000 }{ -365 } \\[1 em]
x & = - \frac{ 20000 : 5 }{ -365 : 5} \\[1 em]
x & = \frac{ 4000 }{ 73 }
\end{aligned} $$
