reescribamos la ecuación
$$116962.1374 x - 15799.9229 = \left(- 3397.7295 x + \left(- 406.8832 x^{3} + 1522.1581 x^{2}\right)\right) + 5949.6816$$
de
$$a x^{3} + b x^{2} + c x + d = 0$$
como ecuación cúbica reducida
$$x^{3} + \frac{b x^{2}}{a} + \frac{c x}{a} + \frac{d}{a} = 0$$
$$1 x^{3} - 3.74101978159826 x^{2} + 295.809379448451 x - 53.4541718606224 = 0$$
$$p x^{2} + q x + v + x^{3} = 0$$
donde
$$p = \frac{b}{a}$$
$$p = -3.74101978159826$$
$$q = \frac{c}{a}$$
$$q = 295.809379448451$$
$$v = \frac{d}{a}$$
$$v = -53.4541718606224$$
Fórmulas de Cardano-Vieta
$$x_{1} + x_{2} + x_{3} = - p$$
