Hi ,
x( x³ - y³ ) + 3xy( x - y )
= x( x - y )( x² + xy + y² ) + 3xy( x - y )
= ( x - y )[ x( x² + xy + y² ) + 3xy ]
= ( x - y )[ x³ + x²y + xy² + 3xy ]
I hope this helps you.

Answer:
= x(x³-y³)+3xy(x-y)
= x(x-y)(x²+xy+y²)+3xy(x-y)
x(x-y)(x²+xy+y²)+3xy(x-y)take out common:
= (x-y)[x(x²+xy+y²)+3xy(x-y)
= (x-y)(x³+x²y+xy²+3xy)
= (x-y)x(x²+xy+y²+3y)
= x(x-y)(x²+xy+y²+3y)
