    Doesn't seem to be much to do besides distributing.

    That's what I originally thought as well, but my answer choices are: a. 14 b. 15√2 c. 5√2 - 4√10 d. None of the above

    Then it's d. None of the above because I can't think how else the problem can be simplified lol. The only other way the answer can be rewritten is\[-2\sqrt{5}(2\sqrt{2}-5)\]
