$$\left. \begin{array} { l } { f } \\ { x ^ { 2 } - 12 x + 20 x - 2 } \end{array} \right.$$
$f\left(\left(x+4\right)^{2}-18\right)$
$$x^{2}+8x-2=\left(x-\left(-3\sqrt{2}-4\right)\right)\left(x-\left(3\sqrt{2}-4\right)\right)$$
$$f\left(x-\left(-3\sqrt{2}-4\right)\right)\left(x-\left(3\sqrt{2}-4\right)\right)$$
$$fx^{2}+8fx-2f$$
