Find a common denominator and add them together. Nothing too tricky here.

A common denominator such as..?
(x+1)(x-2)(x) times those together for a common denominator

For each fraction multiple the numerator and denominator of that fraction by the denominators of the other two fraction e.g the first fraction would be 3(x-2)(x)/(x+1)(x-2)(x)

ok so first off all, look at all the denominators. They are x 1, x-2 and x. You want them all to be the same, so u gotta mulitply them all to get (x)(x 1)(x-2). then u just add and subtract them as normal.
