x1 = atan(3/2)
$$x_{1} = \operatorname{atan}{\left(\frac{3}{2} \right)}$$
x2 = -atan(3)
$$x_{2} = - \operatorname{atan}{\left(3 \right)}$$
x2 = -atan(3)
Suma y producto de raíces

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