x3+y3 = (x+y)(x^2-xy+y^2)
--------------------
R.H.S
(x+y)(x^2-xy+y2)
=>x3-x^2y+xy^2+x^2y-y^2x+y3
NOW after cancelling we get :
=> x3+y3
-------------------
L.H.S
=> x3+y3
L.H.S. = R.H.S

Step-by-step explanation:
x³ +y³ =(x+y)(x²−xy+y²)
= x³ -x²y +xy² + x²y - xy² +y³
After solving this the answee will be x³+y³
so its proved !!
