HOLA !!
ANSWER...
(a² - b²)³ + (b² - c²)³ + (c² - a²)³ / (a - b)³ + (b - c)³ + (c - a)³
Let,
a² - b² = x
b² - c² = y
c² - a² = z
So,
x + y + z = 0
x³ + y³ + z³ = 3xyz ---------(i)
Putting the value of x , y and z in the above equation.
(a² - b²)³ + (b² - c²)³ + (c² - a²)³ = 0
(a² - b²) + (b² - c²) + (c² - a²)
∴3(a² - b²) (b² - c²) (c² - a²).............(ii)
Again,Let,
a - b = p
b - c = q
c - a = r
Since,
p + q + r = 0
p³ + q³ + r³ = 3pqr --------(iii)
Putting the value of p , q and r in the above equation.
(a - b) + (b - c) + (c - a) = 0
(a - b)³ + (b - c)³ + (c - a)³ =
∴3(a - b) (b - c) (c - a).............(iv)
From equation (ii) and (iv),
We get,
(a² - b²)³ + (b² - c²)³ + (c² - a²)³ / (a - b)³ + (b - c)³ + (c - a)³ =
3(a² - b²) (b² - c²) (c² - a²)/3(a - b) (b - c) (c - a)
= 3(a + b) (b + c) (c + a)..
