Find roots of polynomial $$ p(x) = 9x^3+7x+6 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -0.5913\\[1 em]x_2 &= 0.2957+1.0198i\\[1 em]x_3 &= 0.2957-1.0198i \end{aligned} $$Explanation
Polynomial $ 9x^3+7x+6 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
