( 5 - x ) ( 6 - 5x ) ( 2 - x )
= ( 5 - x ) { ( 6 - 5x ) ( 2 - x ) }
= ( 5 - x ) { 6 ( 2 - x ) - 5x ( 2 - x ) }
= ( 5 - x ) { 12 - 6x - 10x + 5x² }
= ( 5 - x ) ( 12 - 16x + 5x² )
= 5 ( 12 - 16x + 5x² ) - x ( 12 - 16x + 5x² )
= 60 - 80x + 25x² - 12x + 16x² - 5x³
= 60 + 41x² - 92x - 5x³
thanks!

Hey
Here's your answer !!
________
( 5-x ) ( 6-5x ) ( 2-x )
= ( 5 - x ) { ( 6-5x ) ( 2-x ) }
= ( 5 - x ) { 6 ( 2-x ) - 5x ( 2-x ) }
= ( 5 - x ) { 12 - 6x - 10x + 5x² }
= ( 5 - x ) ( 12 - 16x + 5x² )
= { 5 ( 12 - 16x + 5x² ) - x ( 12 - 16x + 5x² ) }
= 60 - 80x + 25x² - 12x + 16x² - 5x³
= 60 - 92x + 41x² - 5x³ [ Answer ] .
