Question
Find roots of polynomial $$ p(x) = -3x^2+30x-50 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 7.8868\\[1 em]x_2 &= 2.1132 \end{aligned} $$Explanation
The solutions of $ -3x^2+30x-50 = 0 $ are: $ x = 5-\dfrac{ 5 \sqrt{ 3}}{ 3 } ~ \text{and} ~ x = 5+\dfrac{ 5 \sqrt{ 3}}{ 3 }$.
