उत्तर

Given:

`(x+2)/(x-2) + (x-2)/(x+2) - 4 = 0`

Multiply both sides by `(x-2)(x+2) (x ≠ ±2)`:

`(x+2)^2 + (x-2)^2 - 4(x-2)(x+2) = 0`

Expand: 

`(x^2+4x+4) + (x^2-4x+4) - 4(x^2-4) = 0`

`⇒ 2x^2 + 8 - 4x^2 + 16 = 0`

`⇒ -2x^2 + 24 = 0`

`⇒ x^2 = 12 `

`⇒ x = ±2sqrt3`

`x = 2sqrt3 or x = −2sqrt3`
