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