Find roots of polynomial $$ p(x) = -9x^2+2x+8 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 1.0604\\[1 em]x_2 &= -0.8382 \end{aligned} $$Explanation
The solutions of $ -9x^2+2x+8 = 0 $ are: $ x = \dfrac{ 1 }{ 9 }-\dfrac{\sqrt{ 73 }}{ 9 } ~ \text{and} ~ x = \dfrac{ 1 }{ 9 }+\dfrac{\sqrt{ 73 }}{ 9 }$.
