plz answer quick​

Answer 1

Answer:

Step-by-step explanation:

Given that, a/b + b/a = 1

=> ( a^2 + b^2 ) / ab = 1

=> a^2 + b^2 = ab ------ ( i )

NOW,

we know, a^3 - b^3 = ( a - b ) ( a^2 + ab + b^2 )

                                = ( a - b ) ( ab + ab )  [ from --- ( i ) ]

                                = ( a - b ) 2ab
