➲ Question :-
⦿ Factorise the expression : p³(x-2y) - p²(x-2y).
➲ Assumption :-
◑ Let (x-2y) be a
➲ Solution :-
✎ p³a - p²a [ x - 2y = a]
✒ p (p²a) -1 (p²a)
✒ (p²a)(p-1)
now, as:-
◑ a = x -2y
so,
➟ (p²(x-2y))(p-1)
✒ p²(x-2y)(p-1)
∴ p²(x-2y)(p-1) is the factorise form of p³(x-2y) - p²(x-2y)
➲ Answer:-
✏ p²(x-2y)(p-1)
