Find roots of polynomial $$ p(x) = 2x^4+3x^2+x-180 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 2.9477\\[1 em]x_2 &= -2.9739\\[1 em]x_3 &= 0.0131+3.2042i\\[1 em]x_4 &= 0.0131-3.2042i \end{aligned} $$Explanation
Polynomial $ 2x^4+3x^2+x-180 $ has no rational roots that can be found using Rational Root Test, so the roots were found using quartic formulas.
