x1 = -acos(1/4) + 2*pi
$$x_{1} = - \operatorname{acos}{\left(\frac{1}{4} \right)} + 2 \pi$$
x2 = acos(1/4)
$$x_{2} = \operatorname{acos}{\left(\frac{1}{4} \right)}$$
x2 = acos(1/4)

suma
-acos(1/4) + 2*pi + acos(1/4)
$$\operatorname{acos}{\left(\frac{1}{4} \right)} + \left(- \operatorname{acos}{\left(\frac{1}{4} \right)} + 2 \pi\right)$$
=
2*pi
$$2 \pi$$
producto
(-acos(1/4) + 2*pi)*acos(1/4)
$$\left(- \operatorname{acos}{\left(\frac{1}{4} \right)} + 2 \pi\right) \operatorname{acos}{\left(\frac{1}{4} \right)}$$
=
(-acos(1/4) + 2*pi)*acos(1/4)
$$\left(- \operatorname{acos}{\left(\frac{1}{4} \right)} + 2 \pi\right) \operatorname{acos}{\left(\frac{1}{4} \right)}$$
