Solución detallada
Es la ecuación de la forma
La ecuación cuadrática puede ser resuelta
con la ayuda del discriminante.
Las raíces de la ecuación cuadrática:
$$x_{31} = \frac{\sqrt{D} - b}{2 a}$$
$$x_{32} = \frac{- \sqrt{D} - b}{2 a}$$
donde D = b^2 - 4*a*c es el discriminante.
Como
$$a = -6$$
$$b = - 102 x_{1} + 6 x_{2}$$
$$c = - 11 x_{1}^{2} + 12 x_{1} x_{2} - 6 x_{2}^{2}$$
, entonces
La ecuación tiene dos raíces.
o
$$x_{31} = - \frac{17 x_{1}}{2} + \frac{x_{2}}{2} - \frac{\sqrt{- 264 x_{1}^{2} + 288 x_{1} x_{2} - 144 x_{2}^{2} + \left(- 102 x_{1} + 6 x_{2}\right)^{2}}}{12}$$
$$x_{32} = - \frac{17 x_{1}}{2} + \frac{x_{2}}{2} + \frac{\sqrt{- 264 x_{1}^{2} + 288 x_{1} x_{2} - 144 x_{2}^{2} + \left(- 102 x_{1} + 6 x_{2}\right)^{2}}}{12}$$
a*x3^2 + b*x3 + c = 0
La ecuación cuadrática puede ser resuelta
con la ayuda del discriminante.
Las raíces de la ecuación cuadrática:
$$x_{31} = \frac{\sqrt{D} - b}{2 a}$$
$$x_{32} = \frac{- \sqrt{D} - b}{2 a}$$
donde D = b^2 - 4*a*c es el discriminante.

$$a = -6$$
$$b = - 102 x_{1} + 6 x_{2}$$
$$c = - 11 x_{1}^{2} + 12 x_{1} x_{2} - 6 x_{2}^{2}$$
, entonces
D = b^2 - 4 * a * c =
(-102*x1 + 6*x2)^2 - 4 * (-6) * (-11*x1^2 - 6*x2^2 + 12*x1*x2) = (-102*x1 + 6*x2)^2 - 264*x1^2 - 144*x2^2 + 288*x1*x2
La ecuación tiene dos raíces.
x31 = (-b + sqrt(D)) / (2*a)
x32 = (-b - sqrt(D)) / (2*a)
