X3 (y-z)3 + y3 (z-x)3 + z3(x-y)3 factorise

Answer»

Answer:

FOLLOWING answer

Step-by-step EXPLANATION:

Let a = x - y, b = y - Z, c = z - x

Here, a + b + c = x - y + y - z + z - x = 0

Now if a + b + c = 0 then x3 + Y3 + Z3 = 3xyz

Hence,

(x - y)3 + (y - z)3 + (z - x)3 = 3(x - y) (y - z) (z - x).
