An introduction to adding and subtracting algebraic fractions

[FF35Pilot]

I got this on a past paper for revision, but couldn't find a mark scheme, so

2/x-1 - 3/x

=2x/x(x-1) -3(x-1)/x(x-1)

=2x-3x-3/x(x-1)

=-x-3/x(x-1)?

wondering if anyone could tell me if I'm right?

Great video can you make a more advanced one please. I am stuck on the more complicated ones such as:

2x+1/x^2-x-2 subtract x+2/x^2+x-6

The answer is: x^2+4x+1/(x-2)(x+1)(x+3)

I am not sure how they got to this.
