Question

if X divided by Y + Y divided by X = -1 where x and y not equal to zero then find x cube minus y cube​

Answer 1

Answer:

$\frac{x}{y} + \frac{y}{x} = - 1$

${x}^{2} + {y}^{2} = - xy$

${x}^{2} + {y}^{2} + xy = 0 \: \: \: \: \: ....(i)$

Now

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

$= (x - y) \times 0$

$= 0$
