Question
Find roots of polynomial $$ p(x) = -x^2+269x-12400 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 209.9337\\[1 em]x_2 &= 59.0663 \end{aligned} $$Explanation
The solutions of $ -x^2+269x-12400 = 0 $ are: $ x = \dfrac{ 269 }{ 2 }-\dfrac{ 9 \sqrt{ 281}}{ 2 } ~ \text{and} ~ x = \dfrac{ 269 }{ 2 }+\dfrac{ 9 \sqrt{ 281}}{ 2 }$.
