Step-by-step explanation:
Nombrando los números como
y
,
Planteamos las siguientes ecuaciones:
Sustituimos la segunda ecuación en la primera:
resolvemos para encontrar y:
usando la formula general para resolver la ecuación cuadrática:
donde
Sustituyendo los valores:
usando el signo mas obtenemos que y es:
(no usamos el signo menos, debido a que obtendriamos fracciones y buscamos numeros enteros)
con este valor de y, podemos encontrar x usando:
sustituimos![y=11](/tpl/images/0693/9450/caf29.png)
y comprobamos que el producto sea 253:
