Answer 1

Hey



The given question is :-


[ 5x + 10 / 5 ] ² - x ²



Solution :-


[ 5x + 10 / 5 ] ² - [ x ] ²

This is in the form of ( a ) ² - ( b) ²


So ,

using this formulae , we get


[ 5x + 10 / 5 + x ] [ 5x + 10 / 5 - x ]


= [ 5x + 10 + 5x / 5 ] [ 5x + 10 -5x / 10 ]


= [ 10x + 10 / 5 ] [ 10 / 10 ]


= 10 ( x + 1 ) / 5 * 1


= 2 ( x + 1 )



thanks :)
