Question

solve with working please.. ​

Answer 1

By taking LCM we get ,

x+y= -xy

We know the formula of

$({x}^{3} + {y}^{3} ) = (x + y)( {x}^{2} + {y}^{2} - xy)$

Subsitituting the values of (x+y) we get

$( - xy)( {x}^{2} + {y}^{2} + x + y)$

Answer...

I think the question is wrong it is

xcube - ycube. If you're sure you wrote the correct question this answer is correct.Either it is x/y + y/x=1 or xcube-ycube.
