Question

expand
${(2x - \frac{2}{x}) }^{3}$
​

Answer 1

Step-by-step explanation:

Series expansion at X=0

8 x^3 - 8/x^3 - 24 x + 24/x

(Laurent series)

(converges everywhere)

Series expansion at X=infinity

8 x^3 - 8/x^3 - 24 x + 24/x

(Laurent series)

(converges everywhere away from origin)
