(x-2y)³+(2y-3z)³+(3z-x)³ a=x-2y b=2y-3z c=3z-x If a+b+c= 0, then a³+b³+c³=3abc a+b+c= x-2y+2y-3z+3z-x =x-x+2y-2y+3z-3z =0 a³+b³+c³=3abc =3(x-2y)(2y-3z)(3z-x) Hope it helps ☺ Please mark as Brainliest

a=x-2y
b=2y-3z
c=3z-x
If a+b+c= 0, then a³+b³+c³=3abc
a+b+c= x-2y+2y-3z+3z-x
=x-x+2y-2y+3z-3z
=0
a³+b³+c³=3abc
=3(x-2y)(2y-3z)(3z-x)
Hope it helps ☺
