Question

without finding cubes, factorise (x- 2y) ka whole cube + (2y - 3z ) ka whole cube + ( 3z- x ) ka whole cube​

Answer 1

Answer:

we know that ,if (a+b+c)=0

then ,a3+b3+c3=3abc.

here also,

(x-2y)+(2y-3z)+(3z-x)=0

thus,(x-2y)3+(2y-3z)3+(3z-x)3

=3(x-2y)(2y-3z)(3z-x)

I hope it would help you.
