Find roots of polynomial $$ p(x) = 2x^4+3x^3+3x^2-5x+3 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.4979+0.4157i\\[1 em]x_2 &= 0.4979-0.4157i\\[1 em]x_3 &= -1.2479+1.4169i\\[1 em]x_4 &= -1.2479-1.4169i \end{aligned} $$Explanation
Polynomial $ 2x^4+3x^3+3x^2-5x+3 $ has no rational roots that can be found using Rational Root Test, so the roots were found using quartic formulas.
