Find roots of polynomial $$ p(x) = 3x^2+9x-356 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 9.4962\\[1 em]x_2 &= -12.4962 \end{aligned} $$Explanation
The solutions of $ 3x^2+9x-356 = 0 $ are: $ x = -\dfrac{ 3 }{ 2 }-\dfrac{\sqrt{ 4353 }}{ 6 } ~ \text{and} ~ x = -\dfrac{ 3 }{ 2 }+\dfrac{\sqrt{ 4353 }}{ 6 }$.
