Find roots of polynomial $$ p(x) = 16x^4-16x^3+12x^2+2x-1 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.2395\\[1 em]x_2 &= -0.2963\\[1 em]x_3 &= 0.5284+0.7757i\\[1 em]x_4 &= 0.5284-0.7757i \end{aligned} $$Explanation
Polynomial $ 16x^4-16x^3+12x^2+2x-1 $ has no rational roots that can be found using Rational Root Test, so the roots were found using quartic formulas.
