Hlo friend Here is ur answer : Let a = ( p - q) b = ( q - r ) c = ( r - p ) a + b + c = p - q + q - r + r - p ( All the terms are cut) Then, a + b + c = 0 Identity : If a + b + c = 0 then a³ + b³ + c³ = 3abc ( p - q )³ + ( q - r )³ + ( r - p )³ ➡️ 3 ( p - q ) ( q - r ) ( r - p ) HOPE IT HELPS YOU..
