Question

Q.11 If x/y + y/x = -1 (x, y = 0) find the value of x^3 - y^3

plss solve this i need help plss help me guys ​

Answer 1

(x/y) + (y/x) = (-1)

(x²+y²)/xy = (-1)

(x²+y²) = (-xy)

(x²+y²+xy) = 0

Now, we know that

(x³ - y³) = (x-y)(x²+y²+xy) [formula]

(x³ - y³) = (x-y)(0)

(x³ - y³) = 0 [Ans.]
