Question
Find roots of polynomial $$ p(x) = 30x^2-300x-10000 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 23.9297\\[1 em]x_2 &= -13.9297 \end{aligned} $$Explanation
The solutions of $ 30x^2-300x-10000 = 0 $ are: $ x = 5-\dfrac{ 5 \sqrt{ 129}}{ 3 } ~ \text{and} ~ x = 5+\dfrac{ 5 \sqrt{ 129}}{ 3 }$.
