Find roots of polynomial $$ p(x) = 10x^4+10x^3-100 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 1.5724\\[1 em]x_2 &= -2.0921\\[1 em]x_3 &= -0.2401+1.7269i\\[1 em]x_4 &= -0.2401-1.7269i \end{aligned} $$Explanation
Polynomial $ 10x^4+10x^3-100 $ has no rational roots that can be found using Rational Root Test, so the roots were found using quartic formulas.
