Find roots of polynomial $$ p(x) = 2x^4-3x+5 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.9041+0.6345i\\[1 em]x_2 &= 0.9041-0.6345i\\[1 em]x_3 &= -0.9041+1.11i\\[1 em]x_4 &= -0.9041-1.11i \end{aligned} $$Explanation
Polynomial $ 2x^4-3x+5 $ has no rational roots that can be found using Rational Root Test, so the roots were found using quartic formulas.
