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?
anonymous
  • anonymous
there are two solutions for this one 4 and 4
anonymous
  • anonymous
ohh so theres one solution? just 4
anonymous
  • anonymous
no..two
anonymous
  • anonymous
ha, sorry i keep typing after you answer my ?
anonymous
  • anonymous
every quad. has two solutions
anonymous
  • anonymous
could be real or complex
anonymous
  • anonymous
4 is 4 so you would only write it once if you were solving by factoring or quadratic formula
anonymous
  • anonymous
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?
anonymous
  • anonymous
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.
anonymous
  • anonymous
there r two solutions.. 4 and 4
anonymous
  • anonymous
ok thanks.. It just seems strange putting only the 4 in as 2 different answers. They are both real solutions?
anonymous
  • anonymous
is it multiple choice
anonymous
  • anonymous
yes they are both real obviously....but dont forget to write it twice otherwise teacher might think u got only one root..
anonymous
  • anonymous
no, I select whether there are 2 different real solutions, 2 non real solutions or 1 solution
anonymous
  • anonymous
ok then ...all good
anonymous
  • anonymous
fan me if u liked my help..thanx
anonymous
  • anonymous
2 real solutions
anonymous
  • anonymous
did you enter it in
anonymous
  • anonymous
It's online so it's picky with the format. Do I have this in a root?
anonymous
  • anonymous
no i haven't yet. I will in a sec
anonymous
  • anonymous
it says two DIFFERENT solutions, I still think it is one solution even if is a quad bc 4 is distinct
anonymous
  • anonymous
i just realized it says one repeated real solution..so maybe i should put it under that category?
anonymous
  • anonymous
I think so to, i'll find out!
anonymous
  • anonymous
yes......
anonymous
  • anonymous
YES!!!!!
anonymous
  • anonymous
yep, that was correct. Sorry, my fault I didn't specify that. Thanks for your help guys!

  • anonymous
I knew something wasn't right...you're welcome...fan me please
