Question

l² – (m – n)², Factorise the expression.

Answer 1

hey there!

( L + m - n ) ( L - m + n )

Hope my answer helps!

Answer 2

Solution :

l² - ( m - n )²

*********************************

By Algebraic Identity :

( x² - y² ) = ( x + y )( x - y )

**********************************

= [ l + ( m - n ) ][ l - ( m - n ) ]

= ( l + m - n )( l - m + n )
