x1 = -2*atan(1/3)
$$x_{1} = - 2 \operatorname{atan}{\left(\frac{1}{3} \right)}$$
x2 = 2*atan(2)
$$x_{2} = 2 \operatorname{atan}{\left(2 \right)}$$
x2 = 2*atan(2)

suma
-2*atan(1/3) + 2*atan(2)
$$- 2 \operatorname{atan}{\left(\frac{1}{3} \right)} + 2 \operatorname{atan}{\left(2 \right)}$$
=
-2*atan(1/3) + 2*atan(2)
$$- 2 \operatorname{atan}{\left(\frac{1}{3} \right)} + 2 \operatorname{atan}{\left(2 \right)}$$
producto
-2*atan(1/3)*2*atan(2)
$$- 2 \operatorname{atan}{\left(\frac{1}{3} \right)} 2 \operatorname{atan}{\left(2 \right)}$$
=
-4*atan(2)*atan(1/3)
$$- 4 \operatorname{atan}{\left(\frac{1}{3} \right)} \operatorname{atan}{\left(2 \right)}$$
