    Step 1 is incorrect.

    You must find factors, not do addition or subtractions

    You should rather do this:

    3 (sqrt (464))

    3 (sqrt (232*2)

    3*sqrt (58) * sqrt (4) * sqrt (2)

    3*sqrt (29) * sqrt (2) * 2*sqrt (2)

    6*sqrt (2*2) * sqrt (29)

    6*2*sqrt (29)

    12*sqrt (29)

    Sorry for such a messy answer.
