Question

verify:x3+y3=(x+y) (x2-xy+y2)






​

Answer 1

Step-by-step explanation:

x³+y²=(X+Y) (X²-XY+Y²)

x³+y²=(x³-x²y+xy²+x²y-xy²+y³)

x³+y³=x³+y³+xy²-xy²+x²y-x²y

x³+y³=x³+y³

verified!

Answer 2

Answer:

x³+y³=(x+y)(x²-xy+y²)

To verify let ,x³+y³ be p(x)

p(x)=(x+y)(x²-xy+y²)

p(x)=x(x²-xy+y²)+y(x²-xy+y²)

p(x)=x³-x²y+xy²+x²y-xy²+y³

p(x)=x³+y³

x³+y³=x³+y³
