Answer :
( x² - 2xy + y² ) - z² = ( x - y + z ) ( x - y - z )
Explanation :
( x² - 2xy + y² ) - z²
we know that, ( x - y )² = x² - 2xy + y²
•°• ( x² - 2xy + y² ) = ( x - y )²
=> ( x - y ) ² - ( z )²
We also know that, ( a² - b² ) = ( a + b ) ( a - b )
=> [ ( x - y ) + z ] [ ( x - y ) - z ]
•°• ( x² - 2xy + y² ) - z² = ( x - y + z ) ( x - y - z )
Hence, required expression is factorised.
