Question

Factorise (2x-y)2-11(2x-y)+28

Answer 1

Hi , Thanks the answer and follow me

( 2x - y )² - 11( 2x - y ) + 28

Splitting the middle term , we get

= ( 2x - y )² - 7(2x - y ) - 4( 2x - y ) + 28

= ( 2x - y )[ 2x - y - 7 ] - 4[ 2x - y - 7 ]

= ( 2x - y - 7 ) ( 2x - y - 4 )

I hope this helps you.
