$$\left. \begin{array} { l } { p ( x ) = x ^ { 3 } - 8 x ^ { 2 } + 7 x - 3 } \\ { ( x ) = 2 x ^ { 3 } + 8 x ^ { 2 } - 3 x + 5 } \\ { p ( x ) - 4 ( x ) } \end{array} \right.$$
$q=\frac{-2\times \left(2\left(3\sqrt{12873}+535\right)\right)^{\frac{2}{3}}-37\sqrt[3]{2\left(3\sqrt{12873}+535\right)}-2\times \left(2\left(535-3\sqrt{12873}\right)\right)^{\frac{2}{3}}-37\sqrt[3]{2\left(535-3\sqrt{12873}\right)}-553}{6}\approx -277.706257288$
