We will take this one step at a time

2 over x               =>    2/x

2 over x minus 1   =>   2/(x-1)

2 over x plus 2     =>   2/(x+2)

Now our expression will be,

2/x + 2/(x-1) + 2/(x+2)

The denominator will be      => x(x-1)(x+2)
The numerator will be         => 2(x-1)(x+2) + 2(x)(x+2) + 2(x)(x-1)
