Question

(a+b)^3-a-b factories​

Answer 1

( a + b )³ - a - b = ( a + b )³ - ( a + b )

By taking ( a + b ) as common,

= ( a + b ) { ( a + b )² - 1 }

= ( a + b ) ( a² + b² + 2 ab - 1 )

[ ( a + b )² = a² + b² + 2 ab ]

Answer 2

Answer:

Too easy !

(a + b )³ - ( a + b)

( a + b ) { ( a + b ) ² -1 }

(a + b ) ( a + b +1 ) ( a + b -1 )
