A mi modo de ver, no es necesario desarrollar tanto, si no resolverlo con sencillez en tres pasos: si C elevado al cubo es c3 hacemos c3 = c·c2, igualando con c+c+c y operando, resulta
3C= C·C2, 3= C·C2/C, simplificando C y extrayendo raíz cuadrada a lo dos miembros, obtenemos las soluciones, y la 3ª solución se cumple en la igualdad que C= 0
