Find roots of polynomial $$ p(x) = 8x^3-69x^2+220x-103 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.5602\\[1 em]x_2 &= 4.0324+2.5926i\\[1 em]x_3 &= 4.0324-2.5926i \end{aligned} $$Explanation
Polynomial $ 8x^3-69x^2+220x-103 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
