En resumen
(X² - 25) + (X - 5) (X² - 25) = (X + 5)(X - 5) (X + 5)(X - 5) + (X - 5) (X - 5)[(X + 5) + 1] (X - 5)(X + 5 + 1) = (X - 5)(X + 6) (X² - 25) + (X - 5) = (X - 5)(X + 6).
(X² - 25) + (X - 5)
(X² - 25) = (X + 5)(X - 5)
(X + 5)(X - 5) + (X - 5)
(X - 5)[(X + 5) + 1]
(X - 5)(X + 5 + 1) = (X - 5)(X + 6)
(X² - 25) + (X - 5) = (X - 5)(X + 6).
(X² - 25) + (X - 5) (X² - 25) = (X + 5)(X - 5) (X + 5)(X - 5) + (X - 5) (X - 5)[(X + 5) + 1] (X - 5)(X + 5 + 1) = (X - 5)(X + 6) (X² - 25) + (X - 5) = (X - 5)(X + 6).
