Teorema de Cardano-Vieta
reescribamos la ecuación
$$\left(0.061202 x^{3} + \frac{12753 x}{40}\right) - \frac{845519}{5} = 0$$
de
$$a x^{3} + b x^{2} + c x + d = 0$$
como ecuación cúbica reducida
$$x^{3} + \frac{b x^{2}}{a} + \frac{c x}{a} + \frac{d}{a} = 0$$
$$1 x^{3} + 5209.38858207248 x - 2763043.69138263 = 0$$
$$p x^{2} + q x + v + x^{3} = 0$$
donde
$$p = \frac{b}{a}$$
$$p = 0$$
$$q = \frac{c}{a}$$
$$q = 5209.38858207248$$
$$v = \frac{d}{a}$$
$$v = -2763043.69138263$$
Fórmulas de Cardano-Vieta
$$x_{1} + x_{2} + x_{3} = - p$$
$$x_{1} x_{2} + x_{1} x_{3} + x_{2} x_{3} = q$$
$$x_{1} x_{2} x_{3} = v$$
$$x_{1} + x_{2} + x_{3} = 0$$
$$x_{1} x_{2} + x_{1} x_{3} + x_{2} x_{3} = 5209.38858207248$$
$$x_{1} x_{2} x_{3} = -2763043.69138263$$
