Answer 2

Answer:

So here is your answer

We have to find x³-y³, and as we know that

x³-y³=(x-y)(x²+y²+xy)

As given in the question:-

x/y+y/x=(-1), where x and y≠0

so now continuing the question

first take out the LCM of the equation, which is xy so now

=)(x²+y²)/xy=(-1)

=)x²+y²=(-1)×xy

=)x²+y²=(-xy)

=)x²+y²+xy=0

Now we have to multiply the above formed equation from (x-y)

=)(x-y)(x²+y²+xy)=0×(x-y)

°•° we know that any number multiplied or divided from 0 is also 0

•°• (x-y)(x²+y²+xy)=0

So answer is 0

I hope you can understand by the process I have done so thank you if you are reading this question and I am glad that I have helped you
