    You find a common denominator

    Same as adding any fraction

    \frac{a}{b} + \frac{c}{d} = \frac{ad+bc}{bd}

    For example, number 6:

    

f(x)={-x}+\dfrac{x^2}{x-2}+\dfrac{20}{x^2+x-6}=\dfrac{-x}{1}+\dfrac{x^2}{x-2}+\dfrac{20}{(x-2)(x+3)}

    So you have to find the Least Common Multiple between the three denominators 1, (x-2), and (x-2)(x+3).
