x^3-y^3=(x-y)(x^2+xy+y^2)
x^3-y^3=x^3+x^2y+xy^2-x^2y-xy^2-y^3
x^3-y^3=x^3-y^3
hence proved

yupp
i didnt see that no other person answered this question
tq for giving ur tym
yeah
i am new so dont have more friends or follwers..

(x-y)³ = ( x³-y³) - 3xy(x-y)
↔ (x³-y³ ) = (x- y)³ + 3xy(x-y)
= (x-y) [(x-y)²+3xy]
= (x-y) ( x²+xy+ y²)
✡(x³-y³)=(x-y) (x²+xy + y²). [✡= since]
#proved
