Find roots of polynomial $$ p(x) = 14x^4-37x^2+9 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.5206\\[1 em]x_2 &= -0.5206\\[1 em]x_3 &= -1.5401\\[1 em]x_4 &= 1.5401 \end{aligned} $$Explanation
Polynomial $ 14x^4-37x^2+9 $ has no rational roots that can be found using Rational Root Test, so the roots were found using quartic formulas.
