x1 = 2*atan(2/5)
$$x_{1} = 2 \operatorname{atan}{\left(\frac{2}{5} \right)}$$
x2 = -2*atan(3/2)
$$x_{2} = - 2 \operatorname{atan}{\left(\frac{3}{2} \right)}$$
x2 = -2*atan(3/2)

suma
2*atan(2/5) - 2*atan(3/2)
$$- 2 \operatorname{atan}{\left(\frac{3}{2} \right)} + 2 \operatorname{atan}{\left(\frac{2}{5} \right)}$$
=
-2*atan(3/2) + 2*atan(2/5)
$$- 2 \operatorname{atan}{\left(\frac{3}{2} \right)} + 2 \operatorname{atan}{\left(\frac{2}{5} \right)}$$
producto
2*atan(2/5)*-2*atan(3/2)
$$2 \operatorname{atan}{\left(\frac{2}{5} \right)} \left(- 2 \operatorname{atan}{\left(\frac{3}{2} \right)}\right)$$
=
-4*atan(2/5)*atan(3/2)
$$- 4 \operatorname{atan}{\left(\frac{2}{5} \right)} \operatorname{atan}{\left(\frac{3}{2} \right)}$$
-4*atan(2/5)*atan(3/2)
