How did they do this? What's the step

This is the original equation
[ (8 / (x² - 4)) - (x / (x - 2)) ]

then they got this
[ (8 - x(x + 2))/(x² - 4) ]

What step did they take to get there?
Thanks to anyone that helps.

Given:
8/(x² − 4) − x/(x − 2)

Find a common denominator for x/(x − 2) (i.e. multiply it by (x + 2)/(x + 2)):
8/(x² − 4) − x(x + 2)/(x² − 4)

Now that the denominators are the same, we can add the fractions:
[8 − x(x + 2)]/(x² − 4)

they flipped it around
it's basically the same thing
