Question

`- x - 2 / x(x {}^(2) - 4)`






​

Answer 1

Explanation:

Hello,

First of all we will take any real number x different from 0, -2, +2 as dividing by 0 is not allowed and then we can write

`(( - x - 2))/(x(x^2 - 4))=-(x+2)/(x(x-2)(x+2))=\large \boxed{ -(1)/(x(x-2))}`

because we know that

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

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
