Question
Find roots of polynomial $$ p(x) = 20x^2+70x-3600 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 11.7801\\[1 em]x_2 &= -15.2801 \end{aligned} $$Explanation
The solutions of $ 20x^2+70x-3600 = 0 $ are: $ x = -\dfrac{ 7 }{ 4 }-\dfrac{\sqrt{ 2929 }}{ 4 } ~ \text{and} ~ x = -\dfrac{ 7 }{ 4 }+\dfrac{\sqrt{ 2929 }}{ 4 }$.
