    and so far I have, \[x=8 + or - \sqrt{64-64}\over 2\] I know the 64s can cancel..but what will my answer look like from here?

    4 is 4 so you would only write it once if you were solving by factoring or quadratic formula

    ok. this is an online assignment I have to submit so i'd like to get the formula right. I should just put 4 under the 1 solution?

    we use the quadratic formula...when u can't factorize or it is hard to guess...but here 4 and 4 add up to 8 and gives the product 16.

    ok thanks.. It just seems strange putting only the 4 in as 2 different answers. They are both real solutions?

    yes they are both real obviously....but dont forget to write it twice otherwise teacher might think u got only one root..

    no, I select whether there are 2 different real solutions, 2 non real solutions or 1 solution

    It's online so it's picky with the format. Do I have this in a root?

    it says two DIFFERENT solutions, I still think it is one solution even if is a quad bc 4 is distinct

    i just realized it says one repeated real solution..so maybe i should put it under that category?
