Find roots of polynomial $$ p(x) = 4x^3-6x^2-7 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 1.957\\[1 em]x_2 &= -0.2285+0.9176i\\[1 em]x_3 &= -0.2285-0.9176i \end{aligned} $$Explanation
Polynomial $ 4x^3-6x^2-7 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
