Hi katiethegreat,
To get 2 under the line instead of a surd, multiply the entire fraction by 1,
in such a way, that you get an integer under the line.
This means getting rid of the surd part of the denominator.
To do this, change the sign of one of the 2 values in the denominator to form this fraction.
Either way leads to the answer.
