Answer
The root of polynomial $ p(i) $ is:
$$ \begin{aligned}i &= -3 \end{aligned} $$Explanation
Step 1:
Combine like terms:
$$ \color{blue}{1} -i \color{blue}{-4} = -i \color{blue}{-3} $$Step 2:
$$ \begin{aligned} -i-3 & = 0 \\[1 em] -1 \cdot i & = 3 \\[1 em] i & = \frac{ 3 }{ -1 } \end{aligned} $$This page was created using
