Question

write down the squares of x^3-1/x^3 solve this if you can ​

Answer 1

Answer:

x^6-1/x^6-3(x-1/x)

Step-by-step explanation:

(x³-1/x³)²

(x³)²-(1/x³)²-3x×(1/x)(x-1/x)

x^6-1/x^6-3(x-1/x)

Answer 2

Answer:

(x³-1)/x³

(x³/x³) - (1/x³)

1 - (1/x³)

1 - x^-3

(1-x^-3)²

Using (a-b)²=a²+b²-2ab

(1)²+(x^-3)²-2(1)(x^-3)

1 + x^-6 -2x^-3

1+ 1/x^6 -2/x^3

(x^6 + 1 -2x²)/x^6
