Find roots of polynomial $$ p(x) = 2x^4-3x^3+2x-6 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -1.1607\\[1 em]x_2 &= 1.7395\\[1 em]x_3 &= 0.4606+1.1286i\\[1 em]x_4 &= 0.4606-1.1286i \end{aligned} $$Explanation
Polynomial $ 2x^4-3x^3+2x-6 $ has no rational roots that can be found using Rational Root Test, so the roots were found using quartic formulas.
