(a + b) • (a - c) • (b - c)
Simplify ——————————
(a + b) • (c - a) • (c - b)

Canceling Out :

1. Rewrite (c-a)=(-1)•(a-c) and (c-b)=(-1)•(b-c)

2. Cancel out.

(a + b) • (a - c) • (b - c)
————————————— = 1
(a + b) • (-1)•(a-c) • (-1)•(b-c)

La respuesta correcta es -1. Y si vas invertir los valores, se invierten todos no solo los que te interesa.

Simplificado (a+b)/a+b) y nos sobra (a-c)(b-c)/(c-a)(c-b)
(a-c)(b-c)/(-1){(a-c)((b-c)} Simplificamos de nuevo y nos queda 1/(-1) = -1.
