Question

Solve plz................​

Answer 1

Answer:

c) 0

Step-by-step explanation:

We know that,

x³-y³=(x-y)(x²+xy+y²)          ........(1)

Given that,

x/y+y/x= -1

(x²+y²)/xy= -1

x²+y²= -xy

x²+y²+xy=0

(x²+xy+y²)=0

Multyplying by (x-y) on both sides we get,

(x-y)(x²+xy+y²)=(x-y)×0

From (1), we get,

x³-y³=0

HOPE IT HELPS,
