( b ) 3xy - 6x ( y - z )
= 3xy - 6xy + 6xz
= - 3xy + 6xz
= 6xz - 3xy
= 3x ( 2z - y )
( e ) - 4y ( x - 2 ) - 12y ( 3 - x )
= - 4xy + 8y - 36y + 12xy
= 12xy - 4xy - 36y + 8y
= 8xy - 28y
= 4y ( 2x - 7 )
= 3xy - 6xy + 6xz
= - 3xy + 6xz
= 6xz - 3xy
= 3x ( 2z - y )
( e ) - 4y ( x - 2 ) - 12y ( 3 - x )
= - 4xy + 8y - 36y + 12xy
= 12xy - 4xy - 36y + 8y
= 8xy - 28y
= 4y ( 2x - 7 )
