Question

Factorise : 8x³- (2x-3y)³
​

Answer 1

Answer:

it is in the form:- a³-b³, (2x)³-(2x-y)³

so,(2x-2x+y){4x²+(2x-y)² +2x ×( 2x-y)}

= y(4x²+4x² + y²-4xy +4x²-2xy)

= y(12x²-6xy +y²)

Step-by-step explanation:

Answer 2

Answer:

=(2x)³-(2x-3y)³

=(2x-2x+3y) [4x²+2x(2x-3y)+(2x-3y)²]

=3y(4x²+4x²-6xy+4x²-12xy+9y²)

=3y(12x²-18xy+9y²)

=36x²y-54xy²+27y³
