Since
(x-3)is common on both the sides so we are taking them in the first term and then 2/x
so it stands like this----
(x-3+2/x)(x-3-2/x)
Let x-3 be 'a'
(a+2/x)(a-2/x)
a^2 -(2/x)^2
a^2 -4/x^2
so substitute the value of a in (x-2)
(x-3)^2 -4/x^2
x^2 +3^2 -2 (x)(3)-4/x^2
x^2 + 9 -6x -4/x^2
Hope it helps thou a lot ❤
