Question

x3 + y = (x + y) (x2 – xy + y2)​

Answer 1

I hope that you are able to understand .

Answer 2

Answer:

Step-by-step explanation:

(x³+y³)=(x+y)(x²+y²-xy)

(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+y²+2xy-3xy)

=(x+y)(x²-xy+y²).(proved)

hope you got it.
