Answer:

4

Step-by-step explanation:

(x+1/x)^2 - (x-1/x)^2

(x + 1/x)^2 =>

x^2 + (1/x)^2 + 2(x)(1/x)

x^2 + 1/x^2 + 2 ____ (1)

(x - 1/x)^2 =>

x^2 + (1/x)^2 - 2(x)(1/x)

x^2 + 1/x^2 -2 ______(2)

(1) - (2) =>

x^2 + 1/x^2 + 2 - (x^2 + 1/x^2 - 2)

x^2 + 1/x^2 + 2 - x^2 - 1/x^2 + 2

2+2 = 4

I hope it's correct... I'm not sure because I'm weak at maths
