Question
Find roots of polynomial $$ p(x) = 3x^2+10x+2000 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -\dfrac{ 5 }{ 3 }+\dfrac{ 5 \sqrt{ 239}}{ 3 }i\\[1 em]x_2 &= -\dfrac{ 5 }{ 3 }-5 \dfrac{\sqrt{ 239 }}{ 3 }i \end{aligned} $$Explanation
The solutions of $ 3x^2+10x+2000 = 0 $ are: $ x = -\dfrac{ 5 }{ 3 }+\dfrac{ 5 \sqrt{ 239}}{ 3 }i ~ \text{and} ~ x = -\dfrac{ 5 }{ 3 }-\dfrac{ 5 \sqrt{ 239}}{ 3 }i$.
