Y = Segundo Numero Menor
X.Y = 56 (Ecuacion 1)
X - Y = 26 (Ecuacion 2)
En ecuacion 2: X - Y = 26; Y = X - 26
Reemplazo Y = X - 26. En la ecuacion 1
X(X - 26) = 56
X² - 26X = 56
X² - 26X - 56 = 0 (Ecuacion de Segundo grado para X)
Donde: a = 1; b = -26; c = -56
X1 = [26 + 30]/2 = 56/2 = 28
X1 = 28
X2 = [26 - 30]/2 = -4/2 = -2
X2 = -2
Tomo X = 28
X = 28
Y = X - 26
Y = 28 - 26
Y = 2
Rta: Los numeros son 28 y 2
Probemos:
(28)(2) = 56 Cumple
(28 - 2) = 26 Cumple
