Question
Find roots of polynomial $$ p(x) = 10s^2+4200 $$
Answer
The roots of polynomial $ p(s) $ are:
$$ \begin{aligned}s_1 &= 2 \sqrt{ 105 }i\\[1 em]s_2 &= -2 \sqrt{ 105 }i \end{aligned} $$Explanation
The solutions of $ 10s^2+4200 = 0 $ are: $ s = 2 \sqrt{ 105 } i ~ \text{and} ~ s = -2 \sqrt{ 105 } i $.
