Find roots of polynomial $$ p(x) = 16x^4-48x^3+48x^2-28x+11 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.9159\\[1 em]x_2 &= 1.7021\\[1 em]x_3 &= 0.191+0.636i\\[1 em]x_4 &= 0.191-0.636i \end{aligned} $$Explanation
Polynomial $ 16x^4-48x^3+48x^2-28x+11 $ has no rational roots that can be found using Rational Root Test, so the roots were found using quartic formulas.
