Question

Factorise:
x(y-z)² - a(z-y)³​

Answer 1

Step-by-step explanation:

It is a simple example of identity

if (a+b+c)=0 then a

3

+b

3

+c

3

=3abc

Here (x−y)+(y−z)+(z−x)=0

Hence (x−y)

3

+(y−z)

3

+(z−x)

3

=3(x−y)(y−z)(z−x)

Answer 2

Step-by-step explanation:

x( y+z)(y-z) - a(z+y)(z-y)

x(y-z)- a(z+y)
