Hi ,
Product of ( x - y/5 - 1 )( x + y/5 + 1 )
= [ x - ( y/5 + 1 ) ][ ( x + ( y/5 + 1 )]
**********************"*****************
We know the algebraic identity ,
i )( a - b )( a + b ) = a² - b²
ii ) ( a + b )² = a² + 2ab + b²
*********************"*********************
= x² - ( y/5 + 1 )²
= x² - [ ( y/5 )² + 2 × ( y/5 ) × 1 + 1² ]
= x² - ( y²/25 + 2y/5 + 1 )
= x² - y²/25 - 2y/5 - 1
**If it is really helped u .

You should always try to do your assignment yourself.
