Solución detallada
Abramos la expresión en la ecuación
$$\frac{73 \left(x - 2\right) \left(x - 1\right) \left(x - 3\right) \left(x - 4\right)}{24} + \left(\frac{49 \left(x - 2\right) \left(x - 1\right) \left(x - 3\right) \left(x - 5\right)}{-6} + \left(\frac{29 \left(x - 2\right) \left(x - 1\right) \left(x - 4\right) \left(x - 5\right)}{4} + \left(\frac{\left(x - 3\right) \left(x - 2\right) \left(x - 4\right) \left(x - 5\right)}{24} + \frac{13 \left(x - 3\right) \left(x - 1\right) \left(x - 4\right) \left(x - 5\right)}{-6}\right)\right)\right) = 0$$
Obtenemos la ecuación cuadrática
$$2 x^{2} + 6 x - 7 = 0$$
Es la ecuación de la forma
La ecuación cuadrática puede ser resuelta
con la ayuda del discriminante.
Las raíces de la ecuación cuadrática:
$$x_{1} = \frac{\sqrt{D} - b}{2 a}$$
$$x_{2} = \frac{- \sqrt{D} - b}{2 a}$$
donde D = b^2 - 4*a*c es el discriminante.
Como
$$a = 2$$
$$b = 6$$
$$c = -7$$
, entonces
Como D > 0 la ecuación tiene dos raíces.
o
$$x_{1} = - \frac{3}{2} + \frac{\sqrt{23}}{2}$$
$$x_{2} = - \frac{\sqrt{23}}{2} - \frac{3}{2}$$
$$\frac{73 \left(x - 2\right) \left(x - 1\right) \left(x - 3\right) \left(x - 4\right)}{24} + \left(\frac{49 \left(x - 2\right) \left(x - 1\right) \left(x - 3\right) \left(x - 5\right)}{-6} + \left(\frac{29 \left(x - 2\right) \left(x - 1\right) \left(x - 4\right) \left(x - 5\right)}{4} + \left(\frac{\left(x - 3\right) \left(x - 2\right) \left(x - 4\right) \left(x - 5\right)}{24} + \frac{13 \left(x - 3\right) \left(x - 1\right) \left(x - 4\right) \left(x - 5\right)}{-6}\right)\right)\right) = 0$$
Obtenemos la ecuación cuadrática
$$2 x^{2} + 6 x - 7 = 0$$
Es la ecuación de la forma
a*x^2 + b*x + c = 0
La ecuación cuadrática puede ser resuelta
con la ayuda del discriminante.
Las raíces de la ecuación cuadrática:
$$x_{1} = \frac{\sqrt{D} - b}{2 a}$$
$$x_{2} = \frac{- \sqrt{D} - b}{2 a}$$
donde D = b^2 - 4*a*c es el discriminante.
Como
$$a = 2$$
$$b = 6$$
$$c = -7$$
, entonces
D = b^2 - 4 * a * c =
(6)^2 - 4 * (2) * (-7) = 92
Como D > 0 la ecuación tiene dos raíces.
x1 = (-b + sqrt(D)) / (2*a)
x2 = (-b - sqrt(D)) / (2*a)
o
$$x_{1} = - \frac{3}{2} + \frac{\sqrt{23}}{2}$$
$$x_{2} = - \frac{\sqrt{23}}{2} - \frac{3}{2}$$
