Find roots of polynomial $$ p(x) = 9x^2-2x-4 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.787\\[1 em]x_2 &= -0.5648 \end{aligned} $$Explanation
The solutions of $ 9x^2-2x-4 = 0 $ are: $ x = \dfrac{ 1 }{ 9 }-\dfrac{\sqrt{ 37 }}{ 9 } ~ \text{and} ~ x = \dfrac{ 1 }{ 9 }+\dfrac{\sqrt{ 37 }}{ 9 }$.
